I am using PayPal standard and PayPal express on my current cart. I have a second cart. Can the same settings for both carts? If yes, will the customer be returned to the correct cart?
I know I can't have two PayPal business accounts with the same bank account that it is linked to.
I also have Amazon payments and would like to do the same.
I can't speak for Amazon but for PayPal, I have several different carts paying to the same account…I just use different emails addresses for the different stores.
