You need to figure some things out: What languages, currencies and payment methods can you handle? Not all stores are in English, use USD and take CC payments.
That's what I taught when I saw it.
They claim you can buy at any site in the world. Really? So I can have something shipped from Iran here to me in France, for instance? Will they handle
any currency conversion, get through all financial embargos etc?
The idea is cool, but what it claims to do seems impossible.
I'm a selfish American so I saw that the site could handle all my needs and figured it was good to go! :p
