I saw there is a mastercard which gives people petro points for every dollar they spend on it. I know petro points can be used for gas, so I thought what would happen if I went to a place like Mountain Equipment Co-op and bought a $400 pair of boots, used the card and returned them. After a few dozen pairs returned would I be able to get some gas or would they keep refunding the points everytime I returned something?
Thanks for the input.
