Can I use 40% coupon on upholstery fabric

Not sure

I got 40% off one stock. (Ie: 6 yds of one kind)

It will depend on their sales at the time. If the upholstery fabric is already on sale that week then no.

Not sure. Depends on coupon

If it has has a sale price on it already then no.

GdA! I'm not sure either.... Check the fine print on coupon or call the store. They are usually very helpful. Peace and Blessings
