I'm having a problem with installing a saveasale script to my checkout screens. The problem is that it pops up after someone enters their zipcode to calculate shipping cost. I'd really like to be able to save the shipping cost for the next screen where they enter payment details.....or what would be ideal is if they could enter the zip code info, but make it so it didn't calculate that until the next screen.
Is this possible? At the very least, I'd like to remove that field altogether from my checkout screen.
