You launched a bit too fast the site.
I don't know if it is due to the partnership i proposed but the things are there.
Agree with you, the design is a point but urgently is to fix the bugs.
I mean for legal issue.
I don't know how it works in north America but here in Europe (for example in France or in Germany), your site would be certainly already closed. It is highly risky to play with user's informations such as email adress or worst: Credit card number. As i don't know if you were well informed of that i also would like to point out something. It is badly illegal to record CVV2 number in a database. For all that reason we are only using PayPal.
Anyway, i wish you good luck with your project, i am sure there is a place for everybody.
