This has probably already been said, but I didn't read every post:
When J's has a Coupon Bonanza, like they are currently doing (through today, March 10), you can use multiple coupons in your transaction. When I checked out on Monday and again on Thursday, the clerk actually went through my brochure and clicked on every coupon to see what would be applied. At both trips, I was able to use coupons for every item purchased. I love their batiks, but they are expensive, even at J's. I loaded up on some batiks that I would not have gotten without the coupons. Only a few hours left!
