I know my LQS owner from my quilt guild. She really takes a personal interest in all of her customers and treats them well. I can't get down to her shop as often as I'd like. I shop sales and the clearance racks. I buy books there, but not often, because I like the immediate gratification. Her fabric is good quality and that's important.
I also shop another place that's closer to my work when I need something right away. They don't have a lot of fabric, but I can usually find something that works.
I also shop at a store in Shipshewana in Indiana Amish country that has good fabric and good prices. The staff are very helpful.
I guess I like shopping in person. I haven't seen prices that are that good on the internet once you figure in the shipping and I don't always want to spend a big chunk of money ($50 or more) to get free shipping. Plus I don't trust color matching online.
I like supporting my LQS's because of the "extras" they provide in service and accessibility.
That was long. Sorry.
