I have made 5 transactions in the past 2 weeks 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 lbs On eBay it was $175 plus $50 shipping! I'll pass

Be very careful with the Mercari… Be very careful with the Mercari platform itself when buying or selling. The company’s A.I. Bot scans ads and transactions for activity that could be ‘construed’ as a violation thus prohibited conduct. The system will then simply shut-down your account and attempt to freeze your funds. - Escalating the situation to a human/customer service has no bearing or influence at all. - It almost seems like this is one of Mercari’s revenue streams is to shut-down account and keep your funds. I highly recommend using other well known and trustworthy platforms instead.

Authentication Process is a JOKE! For the most part on average its a good app to sell. HOWEVER if you're looking to sell top designer, Mercari is NOT the place. I sent ALL receipts and pics of recently bought Gucci with tags and the y said is wasn't authentic with all proof of authenticity present, so I don't trust the site as much anymore cause I KNOW it was authentic. Mercurial proceeds to say don't try to list it again.

Seller beware! Seller beware!! I sold an authentic perfume which I have a receipt for proving it came from an authorized retailer. Upon receiving it the buyer claimed it was fake based only on it "not smelling right" and asked Mercari for a refund/return. Mercari said they were initiating a "review". There is no way to contact Mercari or add your side of the story to the review. Within a couple hours they ruled that the item was "not as listed" despite buyer images looking exactly like my listing images so clearly it was the same item I was advertising for sale. Mercari did not reach out to me for my evidence, side of the story, or proof of authenticity, which I would have happily provided. So the buyer is returning it after using some of it. I am out the cost of my packaging materials, and now have an item with less product in it that has been deemed inauthentic by Mercari despite being 100% legit. Glad it was an inexpensive item that I learned my lesson on.

Scammers all the way! As a seller and buyer I will never use them again. Selling, unjustified doubling of shipping charges after sale is complete. This is called bait and switch fraud in any other context. Zero customer service. Kafka-esque circular non communication. Their new return policy is absurd. Buying, their new fees are as absurd as their new return policy.
