Many of the "outdoor" manufacturers seem to "remainder" their goods to Sierra Trading Post:
http://www.sierratradingpost.comIt's been swamped with casual cothing in recent years, but there are still some very good deals to be had if you're diligent. Note that it's got very good search capability (as retail sites go), and you can search by the percentage of discount if you're just "shopping" for deals.
I try to remember to check it when starting to consider a new purchase. They'll seldom have your absolute first choice in an item, but sometimes the discounts are so large you just don't care. Hot items disappear fast, though.
