I got my lightweight stuff from wal-mart. Heavyweight items from a big chain store... In my opinion, most of the items are severly overpriced no matter where they come from. Didn't try your link, but I'm sure it links the Sportsman's Guide, which would probably have some better prices than most chain stores.
