Recovery Project

My project consists of selling tangible glassware products on Amazon Seller Central USA last June I believe. Long story short Amazon has been overcharging me for shipping this whole by allowing customers to choose priority mail and even overnight mail at times and I have been paying this whole time extra for shipping priority mail even if they were given free shipping already. And also they had me believing and manipulating that customers cannot accept their own shipping cost. When I know for a fact a lot of people pay to ship my recent experience with selling on Etsy they robbed me just as bad and I could prove but I'm disadvantaged Im schizoaffective bipolar type diagnosed by the state. This is hard for me to adjust to. I mean common I sold $16,000.00 since June and Amazon got nearly a thousand more than me. I do not even have enough to more money to cover my net 30 Uline.com products they are making me look bad everywhere every time I try to address other issues this is not I have plenty more to write okay
