What is Yankee Swap?
1.
When your Xbox 360 (or similar product) breaks and you go to the store and buy a new one, returning the old, broken one in its place for a full reimbursement.
Remember to switch the serial number sticker and pay with cash. Works well at department stores such as: Wal-Mart, Target, and K-Mart.
Yesterday my Xbox 360 red ringed so I Yankee Swapped at Wal-Mart.
