<prompt> Human: As a graduation gift, Ive gotten about 6 100 gift cards with no cash or ATM access. Theyre vanilla mastercard debit cards and I just want to know if I can get any cash for it.  <response>: Use them to buy groceries. When the balance is getting low, pre-pay the total amount into a tank of gas. You can sell them, but people are not going to pay you 600 for them.
