If I have a 50% JAS coupon and the item I want is on sale, I always have a couple items on my wishlist - interfacing, quilted fabric, rulers and templates. I know all these will not be on sale, so I pick one up. Then my workroom is always stocked and I have been able to use the 50% (or for sure a 60%) coupon. I do not use this plan with a 40% because they have items at 40% often. About 8 years ago, they stopped letting customers change the sale price to regular to use a coupon. They were the only store that still did this and it was an inventory/sales nightmare. One area that seems to cause problems is the difference between instore and online coupons. Most are good both ways, BUT, if there isn't a bar code printed on the coupon, look at the top of it. It will say online only and can not be honored in the store. Hope this helps.
