I've only bought fabric on ebay twice, and both times it was a good buy.
Once I ran out of fabric and the store where I bought it had sold all they had. I took a chance on a purchase and was able to get enough to finish the top and now have some of that red in my stash.
The other time I saw some jelly rolls about to end and the bid was very low. I put in a low bid and got a great deal on some multi-color jelly rolls to make into a Log Cabin (someday).
