OnLine store bug

Hello !

I notice a bug on rc-monster.com online store. When I am logged in, I can't finalize an order. I enter my coordonates, I click on the chekout button. But on the next page, shipping rates are not displayed. I can select UPS or USPS but the checkout button just reload the page.
So, Mike you can delete the empty order #10005140 (I don't know how I could do it). As you can see, I put an another UPS order (So I had to be logged out to do it (not a big problem)).

Regards,

Christophe
