Many of your old fashion big box stores also have an Internet presence. It is worth checking out their online stores for better prices.
Even if you don't want to wait for shipping, the brick and mortar store will often match their online price even if it is less.
Sometimes they also have coupons online that you can print out and use in their stores.
