I have a clean 4.16 installed on my linux server. I want to use google checkout but the problem is about the shipping cost. when i click on google's add to cart button it goes to google checkout page without getting actual shipping cost. It shows just the subtotal. I tried it with anonymous account by the way. I did not log in.
On the other hand i was using pre-login shipping calculation from USPS for 4.1.3 version. It still works great. You can see it on:
www.protechstore.com
I'd like to use same system as protechstore but the difference is about google checkout. Google does not allow to let you take the shipping cost before going google checkout page.
Any help would be appreciated.
