Mine does "End of bolt Thursday" which is the last Thursday of each month you get 25% off any fabric you finish off.
Then we get 25% off our "total sale" one time the week of our birthday and then of course they have the shelf of fabrics that are 25% off.....usually older fabrics but sometimes I can find really good deals on that shelf! My favorite though is the little card, they punch it out and when it is full, you get $20.00 off your next sale. I have used many of those cards....LOL :D
