I never complete an online purchase until I search www.RetailMeNot.com for a checkout discount code. For example, as good as the prices are at www.overstock.com, I always find a discount code from www.RetailMeNot.com for at least 7% off my order. Simply go to www.RetailMeNot.com and enter the address of the website you are shopping at and see if any discount codes are available.
