Pixi and POP Beauty are on HauteLook (up to 70% off)

I haven't tried anything from POP, but the Pixi nail polishes are definitely worth $3 (too small for the $8 full price, I think). They make good eyeshadow too. I've heard brilliant things about the Pixi eyeliners, but haven't tried them myself, yet.

I'd avoid Pixi primers. Haven't been impressed with them. Things are selling out already, so you might want to check it out soon. You need an account to browse, so here is my invite link.

theBalm is still available too, if you want to make your shipping dollars go further.
