I'm like Barbara in that I shop locally first. In fact, if I see something online that I know I just can't live without (how often does that happen to you?), I will call my local LQS and see if they have it or if they can get it. And usually the answer is yes. So though I am paying tax on the items, I am not paying shipping.
I am lucky because I am 15 minutes from one LQS and 30 minutes from another. Also, the LQS that is closest to me has a website, and I can browse and order, then pick it up at the store.
