I sell other things on my website besides CafePress products. How can I combine the two so my customers don have to make two orders?
There are two ways to accomplish this, and they’re totally different. One way is to order the products yourself, and ship them to your customer. You can either ship the products directly to the customer, or ship them to yourself first. This way requires you to bill the customer yourself, but you don’t need to have any special technical skills to accomplish it. You also have to handle any returns or problems yourself. The other method is to set up a shopping cart of your own, incorporate the CafePress products in with the other products, and after you’ve taken the credit card and billing information, to “POST” that information directly to the CafePress server (if you don’t understand the concept of “POST,” you probably don’t want to undertake this method without help). CafePress frowns on this practice (actually, I think they expressly forbid it), but it is possible.
