Ive had the opposite experience between fb and ebay. Never had any major problems with selling on ebay. Ive had the typical no payments after auctions or ive accepted an offer. And a couple ppl who wanted to return something and i had to accept it bc thats how ebay rolls apparently. Fb however, no thanks. Constant PMing from ppl who want to “work out deals” but always want to try to trade instead of buy. Or trying to work out a legit deal and the person doesnt want to pay goods n services or shipping and argues with you bc “man i thought we were cool” or “thats more than its worth to me but I still really want it so im just gonna keep buggin u about it”. Ppl use fb and it works for them. Me? I see it as a broader version of craigslist.
