I shop online because there is not a LQS near me. I like:
Fabric.com - Free ship over $35, low prices, great customer service, fast shipping
Missouri Star Quilt: Daily Deal, Great Tut's, great customer service, $5 shipping, fast shipping
Hancock's Paducah: Unequaled selection, prices at retail but good sales, prompt shipping, good customer service
Connecting Threads: Lower prices (their fabric), books, etc, prompt shipping, good customer service.
I have ordered from others and have never had a bad experience.
