Hancock's of Paducah does not send "back" catalogs. If you request a catalog, they add you to the mailing list and you get one with the next regular mailing. They save a lot of money on postage that way and it helps them keep their fabric prices down.
I'm sorry for all the troubles some of you are having with them, but I have ordered from HoP for years and have been nothing but happy with the quality, the service, and the speed of their delivery. I will continue to use them as my primary online source of fabrics without any hesitation at all.
