False Advertising I purchased a necklace listed as an authentic Tiffany and Co. brand. In January of this year. It is now April and the silver on the necklace is tarnished. Because their policy is 15 days you have to make a complaint they can’t do anything about it at all. Not even investigate and message the seller about false advertising. A real Tiffany necklace will probably not tarnish at 15 days but did at 4 months. Ridiculous. I do not trust Mercari anymore as it appears there is no way for them to regulate the sellers items and advertising

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.

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

Mercari provided me with a duplicate label… I am a seller on Mercari and I shipped out a package with the label Mercari provided. Dropped off the package off to the post office Monday April 29, 2024. Waited 24 hours for the package to start tracking and it never did. I write out a personalized letters to everyone so I remembered the name of the person I sent the item to. Upon looking at the actual shipping label I discovered Mercari SENT ME A DUPLICATE LABEL from a previous order. I reached out to Mercari to ask for help and of course they couldn’t own up to their mistakes and said there was nothing they could do. I spent a majority of my morning calling the post office in a different state trying to intercept this package. I almost got scammed out of 36.00$ thanks to Mercari. Good job protecting me as a seller. 10/10 do not recommend using this platform to buy or sell

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.
