If you run a mid-market retail brand, there is a decision sitting on your desk that nobody is going to ask you to make this quarter, and that will quietly decide your next three years of retention economics. The decision is whether the loyalty programme is a free points scheme the customer joins out of habit, or a paid membership the customer joins because the maths works for them. The 2026 numbers from three very different retailers make the argument look settled.
I come at this as the person who gets the build ticket after a board sets a direction. We have watched clients spend eighteen months inflating a points scheme that the finance team cannot defend, and we have watched other clients put a paid tier in front of a free one and start reporting different metrics inside two quarters. The question for a buyer, from the top of the funnel to the back of the stock room, is which model actually produces the retention curve that pays for the work it takes to run it.
Three retailers filed numbers this year that answer that question with evidence rather than opinion. Costco published them because paid membership is the company. Chewy and Walmart published them because paid tiers have become the piece of the business the market now watches. None of this is new; what is new is that in 2026 the gap between what paid retains and what free retains is wide enough to see in the primary filings.
Below: the three cases, with figures from the companies’ own 10-Qs rather than analyst summaries. Then what any of this looks like inside a real WooCommerce estate, which is the half of the conversation the strategy press never has.
Costco Still Sets the Benchmark Nobody Else Can Hit
Costco is the oldest paid-membership case in retail and still the one every other model is measured against. The company’s 10-Q for the twelve weeks ended May 10, 2026 reports a U.S. and Canada renewal rate of 92.2% and a worldwide rate of 89.7%, with membership fee revenue of $1.373 billion for the quarter against $1.240 billion in the prior-year quarter, up roughly 11%. Over the first 36 weeks of fiscal 2026, membership fee revenue was $4.057 billion against $3.599 billion a year earlier, up 13%. The paid-member base reached 82.9 million from 79.6 million a year earlier, with 148.5 million cardholders overall.
What the figure to pay attention to is not the renewal rate. It is the composition of the growth. The filing attributes the 11% quarterly lift in fee revenue to three sources: the September 2024 fee increase in the U.S. and Canada, new sign-ups, and upgrades from the base tier to Executive. Costco raised the price of the thing, kept selling more of it, and shifted the existing customer base up the tier ladder, all in the same window.
- U.S. and Canada renewal rate 92.2% for the quarter ended May 10, 2026 (10-Q).
- Worldwide renewal rate 89.7% in the same filing.
- Membership fee revenue $1.373 billion for the quarter, up 11% year over year.
- Paid members 82.9 million, up from 79.6 million a year earlier.
The lesson for a mid-market retailer is not to copy Costco. The lesson is what the filing shows about elasticity. A paid-membership base that renews at above 90% treats the fee as a sunk commitment, which lets you raise it without a measurable churn event. A free points scheme does not have that elasticity. The fee is the asset.
Walmart+ Is Doing to Grocery What Prime Did to General Retail
Walmart’s fiscal second quarter ended July 31, 2026. The 10-Q reports membership and other income of $1,837 million for the quarter against $1,652 million a year earlier, up 11.2%. For the six months, the figure was $3,904 million against $3,280 million, up 19.0%. The filing does not break out Walmart+ as a line but names it as the primary driver on the earnings call, and the company has been reporting double-digit Walmart+ fee income growth for several quarters.
On the subscriber side the company has not disclosed a total count, but PYMNTS reported a Morgan Stanley survey putting the program at roughly 28.4 million members at the end of January 2026, growing about 12% year over year on a three-month rolling basis against about 10% the prior quarter. The program lists at $98 a year.
- Membership and other income $1,837M for Q2 FY27, up 11.2% year over year (10-Q).
- Six-month membership and other income $3,904M, up 19.0%.
- Estimated 28.4 million members at end-January 2026, growing ~12% YoY on a three-month rolling basis (Morgan Stanley via PYMNTS, Feb 2 2026).
- $98 annual fee.
The lesson is about where paid membership works. Walmart+ bundles free delivery, early access and fuel savings against a very large grocery basket. The elasticity of the fee lives in the grocery habit, not in the brand. For a mid-market retailer thinking about paid tiers, the question is whether you have a repeat-purchase category that produces enough small-ticket orders a year to make the fee rational for the customer. If the maths does not land for the customer, the fee will not land for you either.
Chewy Shows What a Subscription Does to the Shape of the Business
Chewy’s Autoship is the model worth copying for a mid-market store with a consumable catalogue, because the figures are the ones a founder actually wants: a programme that is not a loyalty tier but the primary ordering flow. The 10-Q for the thirteen weeks ended August 2, 2026 reports Autoship customer sales as 84.6% of net sales, up from 83.0% a year earlier. Autoship sales were $2,817.2 million for the quarter, up 9.3%, against total net sales of $3,330.2 million, up 7.3%. The company ended the quarter with 21.705 million active customers, up 3.8%, and net sales per active customer of $602, up 1.9%.
The 26-week figure is 84.5% of net sales on Autoship. In other words, the recurring order has absorbed the business. There is no points programme to run on top: the subscription is the retention mechanism. Chewy still runs promotional work, but the arithmetic that pays the bills is the one on the Autoship cadence, not the one on first-time acquisition.
- Autoship at 84.6% of net sales for the quarter ended August 2, 2026 (10-Q).
- Autoship sales $2.82 billion, up 9.3% year over year.
- Active customers 21.7 million, up 3.8%.
- Net sales per active customer $602, up 1.9%.
The lesson is to stop thinking about subscription as a secondary retention tool and treat it as the ordering primitive. Where a product category is genuinely consumable, you can retire the points scheme entirely and let the recurring order do the work. The cost of switching customers from one-off to subscription is paid back the moment the second order lands.
The Three Share One Lever
The three cases are different in surface shape. Costco runs a flat annual fee against a warehouse basket. Walmart runs a bundle against grocery frequency. Chewy runs a product-level subscription against a consumables category. What they share is that the retention mechanism is a committed transaction, not a conditional reward. The customer pays something up front to stay in the programme, and that payment aligns incentives on both sides: the retailer makes the fee worth it because they have to, and the customer uses the programme because they have already paid.
A free points scheme is the opposite. The customer owes you nothing and the retailer owes the customer a growing accrued liability denominated in future discounts. The retailer carries the risk; the customer carries the option. That asymmetry is what the 2026 figures above are quietly undoing.
What a Paid-Membership Layer Looks Like Inside a WooCommerce Store
This is the half of the conversation the strategy press never has. If a board decides the next retention bet is a paid tier, what actually gets built, and how long does it take. The honest answer for a mid-market retailer on WooCommerce is that the primitives already exist; the work is in connecting them so they behave like one programme rather than four plugins arguing with each other.
Here is the shape we would ship against this brief, in rough order of effort.
- Membership as a product, not a tag. WooCommerce Memberships lets you model the paid tier as a product with an annual or monthly billing cycle via WooCommerce Subscriptions. One to two sprints to configure, including the renewal reminder flow, the dunning rules for a failed card, and the admin surface a customer-care team can actually use to pause or refund. The reason this piece has to be a product and not a tag is tax, refund policy and renewal accounting all live on products in a WooCommerce estate.
- Benefits engine wired through capabilities. Free shipping on orders above a threshold, member-only pricing on a defined catalogue slice, early access to drops, exclusive variants. All of these resolve to a single question at cart time: does this customer currently hold the membership capability. Two to three sprints to build the resolver cleanly, with a cache layer that does not break on cart updates. The trap we have hit here is that most teams write the discount in six places and then spend a quarter debugging why one of them silently drifted out of sync.
- Member-aware checkout and PDP. The customer needs to see the member price on the product page before they add to cart, not after. One sprint for the PDP banner and the comparison line showing member-vs-non-member. Half a sprint for the cart summary. The reason this matters is that a paid tier only works if the perceived value is visible before the fee question gets asked, and most WooCommerce themes still render the member price inside the mini-cart, which is too late in the funnel.
- Lifecycle integration with the ESP. The membership state has to flow to the email platform as its own trait, so lifecycle flows can branch on it. Two days of work with a mature ESP connector and two weeks with an immature one. The three flows that pay for themselves on day one: renewal reminder sequence at T-30 and T-7, lapsed-member win-back at T+14 and T+45, and a quiet upgrade sequence for the top decile of free customers whose basket shape says they would already be rational members.
- Analytics and the one dashboard the CFO asks for. GA4 custom dimensions for member-vs-non-member on every revenue event. A WordPress-side dashboard that reports fee revenue, member count, renewal rate, Executive-equivalent upgrade rate and net revenue per member against net revenue per non-member. Few hours to instrument, two to three days to lay out, worth more than any of the other pieces because without it the finance team cannot defend the programme to the board at month six when the first renewal cohort comes due.
Rough end to end: eight to twelve weeks for a competent WordPress team to ship the first version and a quarter after that spent measuring and tightening the thresholds. That is faster than most clients expect and considerably slower than a plugin page implies. The reason it is faster than expected is that the primitives are mature; the reason it is slower than the plugin page says is that the integration surface is where the mistakes get made.
If this is sitting on your roadmap and you want a second pair of eyes on it before the board paper is written, this is the kind of work we take on at The WP Clan. We would rather tell you the programme is not a fit for your category than help you build one you will have to unwind in a year, which is a conversation we have had with buyers often enough to say it plainly.
