My fav LQS has a program that when you buy 50 yds (clearance, regular or sale), you get a gift certificate for $40!!! The program doesn't time out (don't have to restart at the beginning of the year). And, it automatically calculates in the computer when it rings your sale....and it lists where you are at with the yardage on the receipt!
The other LQS that I frequent, you have to remember to get your card and give it to them. They store them by the register, but if you forget to get it and give it to them, then you lose out. At the beginning of the year, all points expire. I am not even sure how many yards you have to buy, but only regular and sale price qualify. You only get $25. I have never met the amount apparently....
So, I frequent the other one most of the time!
