I received a hot tip directly from Ricky's NYC (and from some of you as well--thank you!) and I wanted to pass this along:
For 24 hours only (10:30AM EST on 4/23 through 10:30AM EST on 4/24), Ricky's NYC is having a Flash Sale with 20% off ALL makeup (ANY brand – no restrictions) with the coupon code YOUSLAY. Free shipping on orders $50+ (under $50, shipping is calculated depending on how much you buy). Take some time to look through the Ricky's site here because this sale includes lots of brands that you don't often see go on sale!
