It's always good to have an extra pair of prescription glasses around -- just in case. Of course, even buying one pair of glasses can put a dent in your budget. That's why I love this deal from EyeBuyDirect.com. All this week, you can buy one pair of glasses and get the second pair for free. Plus, if the idea of buying glasses without trying them on first is a little weird for you, this site has you covered. Simply go to the EyeTry section of the site and upload a picture of yourself. You can use that picture to virtually try on frames until you find a pair that fit your face. No coupon code is required for the deal and offer expires on July 26th.
