Joann's have been doing that for awhile now...taking any competitors coupns..plus theirs and you can use them all together. Joann's will take all competitors, those printed online nad those from their mailer...all in the same visit.
Today I did that...(well, did it earlier this week to but got some more on line last night!) 50% off regular items (sometimes hard to find!) I had 8 of them. And then another coupon for 15% off ENTIRE purchase including sale items! So I got 1/2 yard of 11 diff fabs for $2.12 each. Kind of like the price of a FQ...$1.99 for 1/4 sq yd.. I got 1/2 yd for $2.
Join their mailing list and get them online and join the mailing list in the store and get them in the mail. I could afford to quilt if I didn't get the ocupons! I used one today for 50% off on $5 batting...plus 15% off that!
