For books however, I went to Amazon. I like delivery to my door... and I wanted to make sure there was product... Now Amazon set back my recieve date 3 times and I'm starting to reconsider. The down side is that NONE of the FLGSs here Have 4E products at all.

There may be a distribution problem in your local area.
I've seen that- I live in the D/FW area, and when 3Ed first came out, I was getting new products about a month ahead of my buddy in Quincy, MA (a Boston suburb).
