I usually buy Warm and Natural from Joann's by the bolt. Good thing to remember is that if you buy it from Joann's website, you can usually get a free shipping code or 40% off. They normally carry it for $315.60 (I think) online for a 90" x 40 yds roll. It is on sale right now for $179 and there is a free shipping code of CYBER333. I just ordered my two rolls!!!
If I buy it in the store by the bolt, they charge me $450 or so for the bolt-then I have to lug it into the car, from the car, up the steps, into the house.
I order online, much cheaper (if you have to pay shipping, it is way reasonable ($17.95 for me). UPS backs up to my house, carries it into my house and places it on the floor. I push it to the stairs and push it down there!!!
The only downfall is that UPS boxes are dusty! But, I can get over it!
There are a lot more sites that sell it by the bolt, just google it.
