I've been selling for a while. It's super easy to use & uploading pics & cropping is the best compared to other apps! The costs are going up! Promoting an item is ltd due to floor pricing which I don't agree with & ltd follows is too! I cross sell on Poshmark & Ebay. Ebay is great for auctions & higher priced items. I'm beginning to sell more on Poshmark bc of the sharing w/out having to lower the price for every offer! Sales are booming for me! Not sure how much longer I'll be using Mercari!
