http://www.amazon.com – Amazon has a large selection of both high quality designer backpacks, and cheap rugged backpacks for those on a budget.
http://www.bagking.com – A staggering selection of both women’s and men’s backpacks. Very nice shipping prices for orders over a certain amount (changes frequently).
http://www.ebags.com – Honestly, if you can’t find what you’re looking for at Ebags, it probably isn’t made. Very decent prices, and fast shipping to boot.
