Once you accept something on Posh, that's if - the transaction is done, and the funds are released to the seller. Posh will not accept your return. Having said that, they wouldn't authorize return due to odor even without you accepting it first hand - as it is something that can not be evidenced. I would suggest to review their return policy before you make any valuable purchases - just to protect yourself in the future.I just bought a Gucci horsebit 1955 crossbody bag from Poshmark. The seller described it as ‘gently used’. When I got it on Saturday I accepted it. On Monday I was going to use it and noticed it has a really bad smell inside. I have tried 3 times to contact Poshmark to request to return this and have not yet gotten a response. I stupidly accepted it before I took the time to look closely at the item. If I ever buy anything again from them I will never accept it prior to the 3 days. This is so frustrating. Buying designer handbags should be fun not stressful!
