Because its easier to add multiple items on the normal webshop IMO, but my favorite part is it saves your info. It's like an autofill that never failsDid u guys seriously not know about the mobile web store? It's the way to go if you're looking to get only one item.why only one? and also to anyone wondering, do not use the "app' supreme offers, it slows the loading. But the "new" section es muy bien for drops.
