Granted, you will have to pay for shipping, but it still might be worth it to you.
If you buy a whole bolt (40 yards) the shipping is only $18, so it comes out to under $6/yard. I know that's probably more than you want to buy, but the shipping charges didn't seem onerous.
Last year there was a special, and folks were getting the whole bolt for under $200 including shipping. You never know.
Shipping for a package of batting was $7.
