Yes. I wait for an item to be 50% off already (the highest discount they'll do in store). Then I use either my 10% VIP card or their 10% or 20% off your whole purchase coupons when they have them. That nets a total discount of 70% to 80% off the 'regular' price. By the way, since Joann's uses MSRP pricing as regular pricing, their stuff is way OVERPRICED to begin with. It's only 'normal' price if it's half off (in my opinion).
Example: books are the COVER price (MSRP). Only a good deal if you can get a book for BETTER than 50%. Since I can get 50% off MSRP books from online stores, with zero shipping. Unless of course, you MUST have that quilting book RIGHT NOW! LOL.... <sigh>
