- Walmart’s online promo system allows shoppers to use grocery-targeted codes FAST30 and SAVE3X to get a $10 discount on Fire Emblem: Fortune’s Weave on Switch 2 by adding a single banana to their cart, dropping the price from $69.97 to around $59.99.
- The workaround, discovered by deal curator Wario64 in mid-September 2026, involves adding a banana to the cart to satisfy the fine print requirement of Walmart’s promo codes, which offer $10 off orders of $35 or more with at least one fresh item included.
- The exploit quickly gained popularity within the gaming community, causing low stock for both Fire Emblem: Fortune’s Weave and online bananas on Walmart’s website, though it remains unclear whether Walmart intentionally restricted banana orders or if demand simply exceeded supply.
A 20-cent banana is now the most valuable item in Walmart’s gaming aisle. A quirk in the retailer’s online promo system lets you use grocery-targeted codes FAST30 and SAVE3X to knock roughly $10 off Fire Emblem: Fortune’s Weave on Switch 2, dropping Walmart’s $69.97 listing to around $59.99. The codes were built for fresh food orders, and applying them to a video game often requires adding a single banana to your cart first. Savvy shoppers know that paying too much at retail is easier than it looks when promo systems work against you.
The story surfaced in mid-September 2026, during the game’s launch window, when deal curator Wario64 publicized the workaround on X. Fire Emblem: Fortune’s Weave carries a standard physical MSRP of $79.99, making any meaningful day-one discount worth chasing.
How the Trick Works
Walmart’s grocery promo codes have a produce requirement, and that fine print turned a banana into a gaming discount.
Walmart’s FAST30 and SAVE3X promo codes offer $10 off orders of $35 or more on eligible pickup and delivery purchases. Their fine print ties eligibility to stores with produce departments and requires at least one fresh item in the cart.
Wario64 found the codes failed to apply consistently when the cart held only the game. His advice, posted directly to X: “if code doesn’t work, try switching to pickup. If that doesn’t work, add a banana (weirdly this worked for me with FAST30).”
Community members quickly confirmed the fix. Adding a single banana, listed on Walmart’s site at approximately $0.20, appeared to toggle the order into a “fresh basket” category that satisfied the promo’s backend conditions.
Some shoppers reported removing the banana after the discount applied and finding the code held for the game regardless. The fruit functioned as an unlock key and nothing more.
Doctor of Credit, a deal-tracking site, had previously documented this dynamic for grocery orders. Its guidance reads: “Make sure the Walmart you’re ordering from has a produce department and then add at least one produce item. Cheapest is usually a single banana.” The gaming community arrived at the same conclusion from a different direction.
The Fallout
The workaround spread quickly enough to put both the game and online bananas into low-stock territory.
The exploit moved fast across gaming and deal communities, and Walmart’s inventory data started showing the strain. GoNintendo reported: “Anecdotal evidence makes it seem like the deal might have worked a little too well, as now not only is Walmart’s website showing low stock for Fire Emblem: Fortune’s Weave, it says singular bananas are now out-of-stock.”
Whether Walmart deliberately restricted online banana orders or demand simply outpaced supply remains unclear. Physical bananas in stores were reportedly unaffected, though some anecdotal claims of local shortages circulated online and could not be independently verified.
Walmart has not publicly acknowledged the exploit or issued any statement clarifying whether grocery promo codes were intended to apply to video game purchases. Both FAST30 and SAVE3X remain explicitly YMMV: results vary by account, region, and timing, with no guarantee either code applies at checkout.
If you want to test FAST30 or SAVE3X on a Switch 2 title at Walmart, the window is uncertain. Promo engines at major retailers rarely leave unintended gaps open once they attract this level of attention. Try store pickup first, and keep a banana on standby.
