90% or more of all online shops are run by local LQS's. So, shopping online, if you're shopping at the small online shops you're most likely shopping at someone's LQS.
If you want to help small shop owners, quit buying your fabric at Wal-mart, Fabric.com, Joannes, Connecting Threads, Hancocks, Beverly's and the other big chains. Those are the places that are killing your LQS's, not the small online shops, most of which are extensions of LQS's or are small mom-and-pop operations.
