I purchased and installed PayPal Express Checkout plugin for my WordPress Theme - Flashlight, so that I would let PP process the payments completely - including shipping costs and taxes.
I disabled shipping and taxes on my website and created shipping & sales taxes rates within my PP account. I thought PP would show the updated cart total with shipping and taxes before going back to my website.
However, they don't get added at all, and the item price gets passed back from PP to my website without any shipping or sales taxes added...or error messages. The final cart screen had two buttons...Place Order and Cancel Order.
My Theme is Flashlight - by kriesi.at/ - Plugins: WooCommerce, WooCommerce PP Express Gateway,
Thanks very much.
Also, I setup business and personal accounts in Sandbox and couldn't figure out how to test what I needed. Documentation is not clear at all.
