Not exactly a sale, but a good deal nonetheless. Gilt City is currently offering store credits if you purchase a Warby Parker gift card from them. Buy a $95 gift card, and receive $25 worth of Gilt City credits, or buy a $150 gift card, and receive $40 worth of credits.
The catch here is that the credit has to be used sometime between November 22, 2013 and February 4, 2014, which doesn’t make it possible to combine it with that Denim Therapy deal. However, if you were planning to buy some Warby Parker glasses anyway, here’s a chance to get a little something extra.
