Costco's return policy is extremely generous. Not only will they cancel and refund your membership fee at any time, Costco also says they "guarantee your satisfaction on every product we sell, and will refund your purchase price" with a few exceptions. Electronics, for example, can be returned within 90 days.
Recently, over on the Costco forum on Reddit, a poster going by pinkieb18 asked, "What is the most ridiculous thing you've seen returned at Costco?"
1. A Christmas tree — in January
She did get the refund, though.
2. A full flatbed cart of eggs
"A full flatbed cart of eggs," a user going by baahbaahsheep wrote. "It made us so angry, since we knew they'd all have to be thrown away."
3. A 7-year-old dog bed
"Used dog bed (from 2011). Covered in hair, filthy, stinky, just gross. Obviously used without issue for 7 freaking years," wrote a user going by somuchlavender.
4. Anything with a VHS component
"Heard someone returned a blender with a VHS instruction video from 2005 a couple days ago," a user going by Rubyred88 wrote.
5. A used cat litter box
"Cat litter box. Still full of cat litter. It stank up receiving for weeks afterwards," wrote a poster called sarynkitamo. "Also a 10 year old garden hose 'because it had cracks in it'."
6. A giant lump of former gummy bears
"My mom always bought those huge bags of gummy bears. She left an unopened one in her car, for who knows how long, during the summer and it melted into a giant gummy log, no sign of bears anymore," wrote a poster going by CoolMilo. "She took it back and they let her return it."
