1.) When paying with a prepaid card such as nfinance is that considered "gift cards" or paying with a "secure credit card" when I'm at checkout. 2.) Why do they ask for your phone number?
Cant answer the first question, but as far as i know they get the # incase there are some problems post order, such as you order a item that is actually out of stock. I think they call to see if you want to swap for something else etc.
