There are no shipping or handling fees: what you see below is what you pay. Using PayPal is cheaper than DigiBuy, as there is less overhead and the savings ($4 or more, depending on the program) are passed to you. State the name of the program as the payment title, and make sure that your email address is not misspelled. A successful PayPal transaction will result in a confirmation message sent to you via email. If you don't receive such a message, this means your transaction did not go through.
