Old Navy website error?
For example, order $100 worth of stuff, and the sale price is $50. You only need to pay $40 at Canadian Tire to get $50 in gift cards. Currently, the website is generating a coupon based on the regular price of the items, so you are getting "super cash" worth $40. In other words, you are spending $40 and getting a coupon for $40. There does not seem to be any restrictions on the use of the super cash.
