If you know your prescription, you can actually purchase glasses online. GlassesUSA.com is an online eyeglass retailer. They offer discounts on great glasses, and have high quality frames and lenses. They have a 100% satisfaction guarantee, as well as a 110% lowest price guarantee (meaning they pay YOU the full price back, + 10% if you find the same glasses lower elsewhere!). Also, if you purchase a pair, or two, or more, there is a refer-a-friend program which earns you discounts. They have a Facebook page (glassesusa) and on Twitter (@GlassesUSA).
Right now, you can order glasses from them for a discount. Customers can take 20% off an order of $80 or more, and Free shipping (to the US) with code FS20.
Also, customers can take 10% off any order of prescription eyeglasses using code Blog10.
I know I am going to go buy another pair, I need a black pair, as I already have pink/purple and a red pair. So, if you get a pair, send me a pic, let me know how you like them!
