First of all, Tarte is having their Friends & Family sale, which gives you 40% off with the code FFAUG and the option of a free gift with purchase (code good from today through August 9th).
Second of all, Tarte has jumped on the rewards program bandwagon (yay!). Every dollar spent will earn you a Tarte Token. After reaching 100 tokens, you are eligible to receive a free deluxe sample with every order. After 500 tokens, you receive a $50 e-gift card from Tarte and if that's not all, you receive a free gift as well as 20% off on your birthday! You can also receive tokens by writing reviews on tarte.com (max of 10 tokens per month) as well as referring friends and family to the new program (10 tokens per friend after first order).
Not too shabby and pretty much in line with the Smashbox program and really even better than the Sephora Beauty Insider program.
Disclosure: This post is ridden with referral codes for the Tarte Rewards Program - I <3 Tarte anyway, but wouldn't be unhappy (ok, I'd be very happy) if you signed up for the program using my link. =)
