I plan on paying about 8k of my student loans off, and I would like to do so through MO's, and I have local places that will sell them using GC's. My question which is somewhat off topic, but how do you obtain the GC's without them being considered a cash advance from the CC company?

End goal of course is to pay the 8k and earn points off the payment and hit minimum spending requirements, instead of just my normal auto payment from my bank account.
