Nintendo Switch 2 owners are buying 20-cent bananas at Walmart to trigger a grocery promo code that takes $10 off pickup and delivery orders, with some reports saying the discount can cut game prices by up to $20. According to BeInCrypto, fans found that Fire Emblem Fortune’s Weave qualified for the code, and some deleted the banana before checkout while the discount still held.

Walmart has not commented publicly, and the banana listing has shown as unavailable at some locations as the workaround spread.
