I've found their wide backing fabrics to be priced a little better than Fatbacks bargain backs. You have to factor in shipping costs too.

I have bought a lot from ebay. Besides looking at the feedback of the seller I also look at the other things they are selling. If someone is selling just a few pieces of fabric, it makes me think that they may not know much about it and I avoid them. I like to buy from the sellers that have a basic little quilt shops.

I have been a buyer on Ebay for years! Never, (knock on wood) had a problem with it. I would suggest looking at the sellers feedback rate and reading their customer comments. If their rate isn't 100% I look and see why. If it was a problem with the item, I won't buy from them. If it was a problem with slow shipping, I will consider it since you really don't have any control for how long something takes to ship. I hope this helps!
