Could be a quilter in Australia...or even Canada...that is still really cheap for them, but they will have to pay outrageous shipping and customs on it!
It really is no different than the people on here that are selling fabrics for $5-$7 per yard that I know we bought at WalMart in the mid 90's for less than $3yd....or at Hancock's in the late 90's for $4.00yd!(or less)
I would venture to say that 80% or more of the fabric sold here is NOT Quilt shop quality and the people selling it are making a pretty good mark up on their older fabrics.
If a person is NEW to quilting, then these OLD fabrics looks NEW at they think $5yd is a bargain, when in fact on those fabrics it really isn't!
I am glad to see the seller is moving her stash at a profit, but I hate to think what will happen if she has to ship that lot overseas and the person claims it was LOST in the mail! She will lose it all..and then some!
