I've used Mercari for a couple of years, but not anymore. The last few months they've raised their selling fees, raised the shipping cost and now keep telling me my packages I ship are over the weight and charge extra shipping fees. I weigh ALL of my items before shipping. (In package with label) I get no say in this whatsoever. They won't even tell you that they're taking the extra fee out of your profit until AFTER the sale is complete. What a joke! They won't let me delete my account!!
