When a quilt shop carries Quilter's Select, they have to sign a contract that says they won't sell them online. Maybe The Quilt Show and Missouri Star have a different contract than your local quilt shop.
I went to the lqs today and I asked the owner if it was in the contract to not sell QS online. She said she would never have signed a contract like that. Online sales are what keeps her shop open for customers and most shops have an online store.
