They have a strange way of calculating as they round a lot but 1x is about .4% I believe, so 50x would give you 20% back in CT money. If you have their credit card it would be 10x plus 50x which is about 24%.
My insert coupon $3 wub 2 says limit one coupon redemption per customer. I also have a $1 tearpad coupon that also says one coupon redemption per customer.
