On top of Sephora's yearly free birthday gift, they're also giving away free Sephora Collection rouge cream AND 15% off any purchase today only on their site (it's the first promo code listed below.) Nice job, Sephora. I've always wanted to be a rogue agent!
It took a while for the form to submit, but it finally went through and redirected me to Sephora's homepage, so I think this is still active.
Get a freebie, get a discounted item, and then get a birthday gift. Not bad!
