How Did the Americano Coffee Set Reach 19.6 Yuan?
Mstand's mini-program briefly showed a checkout discount that let new members pay 19.6 yuan for a three-visit card package priced at 100 yuan plus a 28-yuan Americano coffee. The error appeared in the payment page discount section during a limited-edition denim bag promotion, and screenshots spread quickly online.
The discount came from a 50 percent off new-user coupon that the system misread as a 100-yuan member discount at checkout, according to the shared account. Many users registered to repeat it, but few succeeded and most saw ordinary sour americano pricing instead of the error price. Mstand has not explained how it will handle the case.
Mstand has long been known as a "merchandise maniac," and recently the brand launched two limited-edition denim bags, quickly triggering a buying frenzy. However, some consumers discovered during checkout that a 100-yuan member discount appeared in the discount section of the mini-program's payment page, which when stacked meant they only needed to pay 19.6 yuan to get a three-visit card package originally priced at 100 yuan plus a 28-yuan Americano. After this anomaly was shared online, a large number of users rushed to register as members on the mini-program to try to replicate it, but few succeeded. Was it a system glitch or a traffic-driving tactic? How will the official side handle it afterward? This article will sort out the full picture of the incident.

Mstand, long known as a "merchandise maniac," recently launched two limited-edition denim bags. Compared with the previous "grocery basket," the new backpack has a more minimalist and streamlined design, and its durability has also improved, so it attracted a large number of users to place orders as soon as it was released.
At the same time, when a customer was purchasing a limited-edition promotional package through the official mini-program, they discovered that a 100-yuan member discount appeared prominently in the discount section of the checkout page. With this discount applied, the originally 100-yuan limited three-visit card package plus a 28-yuan Americano actually cost only 19.6 yuan.
After discovering this anomaly, the customer immediately asked a friend to try placing an order as well to see whether the same operation could be replicated, and from this summed up the pattern: after newly registered users complete their membership information, the official side gives them a 50%-off coupon, and at checkout this coupon turns into the 100-yuan member discount on the payment page because of a system issue. In other words, this was originally supposed to be a benefit for new users.
After this method of buying the package at an abnormally low price by exploiting the system anomaly spread online, many netizens who had long admired the denim bag could not hold back and went to the mini-program to register as members and add the package to their shopping carts, hoping they too would be favored by luck at checkout.
Under the related sharing posts, some users who successfully took advantage can be seen happily posting their orders, confirming that the method indeed worked. But more people reported that after trying operations such as switching stores and repeatedly refreshing the page, the checkout amount still never had that 100 yuan reduced.
In response, some suspected that the mini-program glitch had already been noticed and fixed by the official side, but users who successfully placed orders believed that as long as they kept refreshing, they might at some moment happen to catch the bug.
Undeniably, affordable and good-looking merchandise is extremely attractive to deal hunters, enough to prompt them to register as members and order packages in order to grab a bargain.
Thus, in the two days after the system anomaly was discovered, some persistent users kept refreshing and trying in order to get the merchandise and coffee at a more cost-effective price. However, judging from feedback on social platforms, very few people could actually exploit this loophole to buy the package at the lowest price.

Many netizens who tried repeatedly but failed began to question the authenticity of the sharing posts, guessing that the so-called mini-program system bug might just be a tactic to attract more people to register as members: "I always suspected it was a traffic-driving post to bring in a large number of new members," "That's just traffic-driving; many people probably registered as members."
Some also commented that they did successfully catch the bug and place an order, but afterward a store employee called to explain that it was a system malfunction and that it would not be shipped, suggesting they apply for a refund. Other users said that after successful payment, their orders were canceled by the store.
At present, the ordering anomaly in Mstand's limited-time campaign this time should have been fully fixed, and on the official mini-program it is no longer possible, as netizens shared, to use the 50%-off coupon for newly registered members to exploit the merchandise deal. Perhaps the 100-yuan member discount those lucky users posted was, in the end, only a beautiful dream that could not be realized.
