Okay, I may finally be certifiable! In my neverending quest for more miles, I have come up with my most creative miles earning plan yet. I recently got my teen daughter a Visa Buxx card (it's a prepaid Visa card) and her allowance is automatically transferred from my miles earning Mastercard weekly. As well as any other school expenses. Instead of giving her cash, I just log in, load money to her card, and send her shopping.

Miles for teen spending. You gotta love it!
