Our frequent buyer program is a thank you for shopping with us. When you purchase 11 pairs of shoes, we take the average retail price of those 11 pairs and apply that average as a coupon to pair number 12. We keep track of your purchases by using your phone number, you are able to put anyone you choose on your account (spouse, parent, child, etc). For example, you buy 11 shoes that total $1100.00 then when you purchase your 12th pair you would receive $100.00 off that pair of shoes. We have no time limit on the program, therefore you don't need to purchase all 11 pairs in a year or use your 12th pair discount within a certain period.
