I always shopped multiple sites for new/used items, and I've always had good experiences with sellers on Mercari. However, I went to Mercari today to make an offer/purchase, and I couldn't understand why the amount was so much higher than what I'd offered. Turns out, they've added a "processing fee" and a "payment fee" that cost me nearly $3 added to my purchase!!! Just wanted to say goodbye Mercari! You're the worst!
