I have made 5 transactions in the last 2 weeks on Mercari. All went smoothly until the last one, when a subwoofer arrived that wasn't packed to well and was damaged. I contacted Mercari and customer service was awesome. Yes, there is payment processing fees and service fees, but I still paid less on Mercari than I would have on eBay. One of my purchases was a fairly new Denon Networking 7.1 receiver was $75 plus $40 shipping. The thing is absolutely amazing and weighs 30 lbsOn eBay it was $175 plus $50 shipping! I'll pass
