Having issues with multiple POD apps during checkout, any solutions?

Hello all,

I’m very new to this and not sure how to find the answer to my question.

I’m using Printful and Printfy. I went in to my site, Mamisays.com, as a customer and added one product from each POD supplier to my cart. When I got to shipping, I got a message that shipping was unavailable to my address. However, when I tried checking out each product individually it was fine. What do I need to fix?

Thank you!
