Commenters discussed the sketchy ways they’ve witnessed smaller businesses make a profit by reselling items, and, as it turns out, the farmer’s market is infamous for reselling Costco goods. When one user commented, “I've seen 'farmers' sell mangos at markets in Colorado,” another exposed the practice saying, “the fruit still has a plu sticker on it.”

Many pointed to smaller operations that used Costco as their main supplier, with one commenter claiming to be a Costco worker noting, "A donut shop […] sells our muffins for $4 each and our croissant for $3 each." While Costco muffins are sold at $7.99 for two six-packs, a pack of 12 croissants retails for $7.45 — meaning companies can make enormous profit using this strategy.
