There are different important things on buying on an online eCommerce website, Most of the customer including me wants to have fast shipping and free shipping if possible of course. Quality service is a must also, As a customer we want to have the order we get on a condition we are expecting, Stealing and mishandling of parcel is quite common these days because of the irresponsible shipping couriers that can give a bad reputation to the online shop. Security is also needed in terms of we are buying items using crypto so we expect an online eCommerce website to have good security that it can't leak our info in their database.
