Ditto to above ... plus
They always have an area with marked down bolts, usually ends of lines or old stock (sometimes quite old!). Good buys can be found there, if you are lucky. Plus periodically they will offer them at a further discount price, advertised in their flyers or via emails.
It is not uncommon for them to have a % off sale for Christmas fabrics periodically. Also, sometimes for other lines or types of fabrics (eg. fleece, flannelette, upholstery, etc.)
Another thing to watch ... if there is more than one bolt of the same fabric, check the price of all of them. They are priced according to what price they come in at. Sometimes that can mean quite a $ difference ... if you are lucky!
Keep in mind, they are buying fabric in two different ways. One, would be the same as other stores, and the prices will be in line with whatever the current pricing is. The other, they buy job lots at a set price, and pretty much only know how much fabric is arriving. Not knowing what it may be.
I always check their website for coupons before I go. Sometimes they can be quite helpful towards discounting items ... not just in the fabric department.
