kmessinger on "Shipping Costs"

I have an e-commerce photography site where I sell images. Is there a way to automatically calculate shipping costs based on what is ordered and their zip code?

That depends on which e-commerce plugin you're using. Did you ask in their support forum?

I believe I am using Photocrati 4.9.3. I will check with them.

Isn't Photocrati part of WordPress?

No. Support for your theme is at http://members.photocrati.com/
