I've setup the USPS module but when I go to my cart and do the estimate shipping and taxes the popup says "please enter a valid zip code for the recipient" which I have already done. Also does anyone else notice that when you click on the "Estimate shipping & Taxes" the little popup window appears really far down on the screen, so that if you didn't scroll down you'd think it wasn't there?
I then tried to just checkout and see what shipping options were available but the only one that showed up was the flat rate shipping that I enabled.
Any help would be so much appreciated.
Thank you

Sherry
