99 Miles by Burger King
- Image via Wikipedia
Burger King has a holiday web promo for sending holiday greeting cards for $1 each. However each card contains an actual $1 bill inside, which means that it’s possible to get free miles/ points by using your favorite credit card. However promo has limit of 99 cards per order and you have to type in the address separetely for each card. So earnings potential is limited and even getting the 99 miles does take time.
