The Coupon That Ate November
A Foshan merchant spent eight years learning the math. This year the platform took the math away.

Li Wenjing keeps a notebook in her warehouse office, and for eight Novembers it was the most important object in her life.
She sells storage baskets and bathroom organizers out of a 400-square-meter unit in Foshan, twenty minutes from the ceramics markets where her father sold tiles before the housing slowdown. The notebook has columns. Deposit expansion on the left. Cross-store full-reduction in the middle. Store coupons, category coupons, coin redemption on the right. Every October she sat with her operations manager and worked out which combination of coupons would let her list a 79-yuan basket at a price that looked cheap without actually being cheap.
"We called it Deploying troops. "You put a 10-yuan store coupon here, you let the cross-store coupon carry the rest, and you pray the customer doesn't notice they paid 61 yuan for something you could have sold for 55."
By the second week of November, the notebook was always a mess. Crossed-out numbers, arrows, a page where she'd tried to model what happened if a shopper padded their cart with a 12-yuan phone stand and returned it the next morning. That page has a coffee ring on it. She remembers the night she made it. She remembers thinking, if one in five of them does this, I'm paying for their coupon out of my own margin.
This year the notebook is empty.
On October 12, JD.com started selling in-stock goods. No deposit, no pre-sale, no waiting for a midnight that never quite arrives. Tmall opened pre-sales on the fifteenth and moved to in-stock on the twentieth. Douyin started its opening sale on the fifteenth. Taotian will keep selling until November 13, which is thirty days of a shopping festival that used to be one night.
Li Wenjing found out the rules had changed the way most merchants find out. A younger seller in her supplier WeChat group posted a screenshot. No cross-store full-reduction. Official direct discount, up to 15 percent. One item qualifies. No padding.
I read it three times, she said.
Her first reaction was relief. Her second reaction, roughly an hour later, was the one that kept her up. If everyone gets a flat discount and nobody can pad their cart, then the only thing left is the price on the label. And if the only thing left is the price on the label, then a merchant with a factory in Yiwu that runs three shifts is going to eat her alive.
Down in Shenzhen, Zhou Kai is the kind of shopper the old system was built for.
He is 29, works in hardware sourcing, and used to treat Double 11 like a competitive event. In 2021, he bought a robot vacuum, a rice cooker, and two pairs of running shoes he did not need, because the coupons only stacked if the cart cleared 1,200 yuan. He built a spreadsheet. He color-coded it.
"Then one year I did the thing everyone does," he said. "I added a 39-yuan towel set to hit the threshold, paid, and returned the towels the next day."
He did it three years running. Once he returned a yoga mat. Once, a set of chopsticks that arrived in a box bigger than his laptop. The refunds cleared. The coupons stuck.
"I wasn't trying to cheat anyone," he said. "The system told me the towel set was worth 39 yuan of discount. I believed it."
Last year he stopped. Not out of principle. He changed jobs, the hours got longer, and the spreadsheet stopped feeling like a game. This year, when he opened Taobao and saw "official direct discount, up to 15 percent," he bought a desk lamp and closed the app.
"I didn't save as much," he said. "But I was done in four minutes."
The policy arrived on October 10, two days before JD.com opened, which is either a coincidence or the least coincidental thing about this year's festival.
The Ministry of Commerce and six other departments issued a notice on the "Five Excellences" action for quality e-commerce. The language is bureaucratic, and in Chinese bureaucratic language the important part is usually the verb. The verb here was Correct and govern. The object was automatic price matching and the lowest-price-across-the-entire-internet rule.
For two years, automatic price matching had been the quiet engine of the whole thing. A platform watches your competitors' prices. If it finds a lower one, it changes yours. You can opt out. If you opt out, your traffic drops.
Last June, screenshots circulated in merchant groups showing a JD.com procurement staffer telling sellers that any product caught by the price comparison system would be discounted another 20 percent on top of the matched price. A seller pushed back. The reply, according to the screenshots, was that he could choose not to participate, and that he was welcome to look for opportunities on rival platforms. JD.com never confirmed or denied the exchange. Sellers on Pinduoduo and Taobao described the same arrangement in different words.
Li Wenjing turned the feature on in 2023 and turned it off four months later, after a competitor dropped a similar basket to 49 yuan and her price followed it down.
"I sold 900 units that month," she said. "I lost money on every one."
What is left, when the coupons are flat and the padding is gone and the price-matching machine has been told to sit down, is the part of retail that does not photograph well.
Warehouse layout. Shipping contracts. How fast you can restock a SKU that spikes on a Tuesday. Whether your cardboard supplier gives you a 30-day term or a 60-day term. Li Wenjing spent the last two weeks of October doing something she has never done before a Double 11. She drove to her packaging supplier in Dongguan and renegotiated. She got the per-box price down by 11 fen. On 200,000 boxes that is 22,000 yuan, which is roughly what she used to lose to padded-cart returns in a single promotional window.
She also cut her SKU count from 340 to 210. The notebook is empty, but the spreadsheet she built to decide which 130 products to drop is nine tabs deep.
"The old game rewarded the person who was best at hiding the price," she said. "The new game rewards the person whose box costs 11 fen less."
The numbers behind all of this have been visible for a while, if you were looking at the right ones.
In 2019, Double 11 sales across the whole internet grew 51.8 percent. In 2020, 43.3 percent. In 2021, 12.2 percent. In 2022, the major platforms quietly stopped publishing daily reports. The hourly GMV ticker that used to run on Alibaba's media screens disappeared. Nobody issued a press release about the disappearance.
Meanwhile, from January to August this year, national online retail sales of goods grew 4.3 percent. Food grew 15.9 percent. Clothing grew 4.9 percent. Household goods, which is Li Wenjing's category, grew 1.1 percent. Instant retail, the category that covers everything from a 30-minute grocery run to a same-day phone charger, kept growing at double digits.
The 2025 Double 11 figures landed at 1.695 trillion yuan across all channels, up 14.2 percent. Read that number slowly. Comprehensive e-commerce grew 12.3 percent. Instant retail grew 138.4 percent. The festival is not dying. It is being absorbed by something faster and closer.
Zhou Kai bought his desk lamp on October 16 and it arrived the same evening, because the listing had a same-city warehouse attached to it. He did not open a spreadsheet. He did not return anything.
Li Wenjing shipped her first batch of in-stock orders on the twelfth, three weeks before the old festival would have even opened its pre-sale window. Her return rate for the month is running at 9 percent. Last year, in the same window, it was 31 percent.
She is not celebrating. The flat discount means every seller in her category is now advertising the same 15 percent, and the only differentiator left is what the customer sees when the box arrives and whether the box arrived at all. She has a competitor in Jinhua who is listing a near-identical basket at 3 yuan less. She has not dropped her price. She has been watching what happens to him.
"It's a cleaner game," she said, closing the empty notebook and putting it in a drawer. "I'm not sure it's an easier one."
The drawer has eight other notebooks in it. She has not thrown any of them away.
