I got this in my email from Sports Authority. There are coupons you can print out for discounts on running shoes (and other things). If you need new shoes (every 300-400 miles of training) then this may be a good place to get them.

Also, I found another website that has great prices on shoes. However, you will want to try them on at a store before buying them online. (FREE SHIPPING TOO!) PLUS- they tell you what kind of shoe it is (neutral, support, motion control, wide, narrow etc.) It really is a resourceful website.
