I was just on Retail Me Not's E.L.F. page, and saw a coupon code for "60% off your entire order until midnight". The code is SIXTY. I applied it to my order on E.L.F.'s website and it worked! I currently have over $20 worth of products in my cart, so I don't know if there's a minimum amount you have to spend for this to work, but go ahead and try it. I want to say this is a promotion for July 4th but again, I'm not sure. Unfortunately the coupon code doesn't explain much.
If you're planning on placing an order with E.L.F., this would be a good time! (I'm not sure I'll end up making a purchase this time around; for now I'm on another mini makeup ban :/ )

Update:
Thanks to Andi over at Discount Decadence for finding out that you need at least $25 worth of products in your cart before this coupon code can be used.
(FYI: I'm not affiliated with E.L.F. in any way. I wish!)
