Costco Workers Reveal Shoppers' 8 Craziest Returns

From electronics to used bed sheets, members can return almost anything at any time. That said, some returns are so clearly outrageous that employees have to say no. Costco workers have shared stories of the most ridiculous returns on Reddit, including used underwear, rotten salmon, and other shocking products. Read on for some of the craziest returns in retail.

You shouldn't leave raw fish in your car for more than a few minutes, let alone months. But that's exactly what one oddball shopper did.

More than 10 years after purchasing it, a Costco member tried to return a dirty, rusty, grass and oil-covered lawnmower, a superfan shares. While this customer was clearly abusing the store's policies, he received his money back because the lawnmower had, in fact, stopped working.

A bag of oranges isn't as outrageous as a months-old rotten salmon or years-old used underwear. Still, returning a bag of oranges every month because just a few go bad is clearly taking advantage of Costco's return policy, and that's precisely what one Costco member did, a Redditor writes. But this time, the retailer took notice. "After about six months her account was flagged and she was given a choice to return her membership or accept the fact that oranges go bad if you don’t eat them fast enough," they explained.
