I am using the PayPal express checkout module that is in zen cart. I just noticed that if a customer makes a purchase and then uses the PayPal check out button, the shipping quote is not added in. The customer will only pay for the product and not the shipping.
I've looked and haven't found a setting to change that. When the user doesn't use the button he/she gets to choose the shipping, there is only one, then when they go to PayPal the charge is correct. Both product cost and shipping. Is there a way to fix that or should I be using one of the other PayPal modules.
