I used to go to my LSS all the time, but haven't lately simply because they can't keep up with carrying all the latest and greatest. When I first started out, I wasn't as picky and bought what they carry, but now that I've accumulated so much, I'm more selective. Now I tend to just shop online at sb.com.
That being said though, I do miss touching and feeling the product before purchasing. I recently purchased papers online from 2 manufacturers whom I've never bought stuff from before. One (Jillibean Soup), the quality was fantastic. The other I was not so pleased and wouldn't have bought if I had actually felt it at the store. There are other times where I'd ordered something online and the color wasn't quite what I'd anticipated.
In short, there are good and bad things about online vs. brick and mortar stores.
