Mercari is a scammers Paradise. Seller sold me a used item marked as New. Mercari customer service emails the buyer not to rate the seller if you are unhappy with your purchase. While you are waiting to resolve an issue, Mercari then AUTOMATICALLY rates the seller 5 of 5 stars and marks the sale "Complete," telling you there is NOTHING they can do now that the sale is complete. Avoid Mercari. Very diffict to navigate the app if you are having trouble.
