(note: I also sent an email to customer service concerning this.)
I have 27 items in my Shopping Cart.
When I attempt to checkout and click the 'Place Your Order' button, I'm kicked back out to the Shopping Cart.
Can you submit the order on your end?
(My shipping and payment information is correct in the system.)

If this would help your tech support/web staff, here is what's happening:
//paizo.com/store/cart
<Press ‘Proceed to Checkout’>

<Press #4 ‘Place Your Order’ tab>
//paizo.com/cgi-bin/WebObjects/Store.woa/wa/checkout (summary page)
<Press red ‘Place Your Order’ button>
Sent back to //paizo.com/store/cart , order not processed.
