11. When do I pay ? You pay the seller of the product in the USA directly.   When you register the shipment with ShopUSA you enter your credit card information.  ShopUSA will not charge your credit card until after the product has been received in the ShopUSA warehouse.  ShopUSA will not charge your credit card if the product does not arrive in the ShopUSA warehouse.

17. What happens if I forget to register my shipment at ShopUSA?
If you forget to register your product, ShopUSA will not be able to forward your shipment.  ShopUSA will store your shipment for 30 days.   Meanwhile, the ShopUSA service department will try to notify you via email.  You must then complete the registration. ShopUSA does not keep any credit card numbers on file. 

Please remember to always register your shipment every time.

22.  What if my credit card is denied by a the US seller? Some on-line retailers require you to use the same shipping and billing address.  Check with your credit card issuer if you can add your ShopUSA address as your secondary billing address.  Then register your ShopUSA address as both your shipping and billing address.

 

Sometimes it is simply to cumbersome to buy from sellers that do not accept your credit card. You might find same or similar product from many different sellers - e.g http://www.amazon.com/
