Found a t-shirt I liked on CafePress & ordered it. Chose the least-expensive option for shipping. When I got to payment page, I assumed the option I chose was in place, & didn't find out til following page that it was a higher shipping charge that was applied. Received an e-mail order confirmation from CafePress. Could not go back on the site to change this, but since I'd chosen AmazonPayments for payment, I contacted it about this, the following day. The day following day after that, I get an e-mail from CafePress staing that my order has shipped.
Suffice to say that I cannot & do not recommend CafePress as a site to do any business at. Stay away from it. There are other places to get whatever CafePress sells, leave it alone.
