since you are promoting an e-commerce platform, you need a lot of partners for this project. aside from the mentioned partners on your op, do you have additional establishments/shops on the works? because if you are aiming like the amazon in crypto sphere, you should have tied up with vast number of shops. not just only couple of partners

also, how about the shipping charges? usually my problem with online purchases is the high cost of express shipping. have you discuss that already within your group or this will just be for trading purposes?
