After falling hook line and sinker for these babies, I figured you should too. The lovely folks at Penn Avenue are offering you 10% off your order with the code YELLOW and well, they figured they should give a pair away to one of you lucky cats as well. Up for grabs is either one pair of prescription glasses (non-horn) or a pair of sunglasses (your choice). If that's not totally exciting I don't know what is. Oh I know. This.
