Any Elle’s Studio coupons or promo codes?

Not that I'm aware of.

However, I would hold on a month or so. She usually does a big spring sale in April (not quite as big as Black Friday, but the discounts on the marked down items are just as good...and there are grab bags just like Black Friday). Last year, it was a few weeks later than normal, so not sure if she is going to plan on keeping it at last year's time frame or go back to when it usually is (which prior to last year, was at the start of the month).
