Urban Decay Primer Potion Update

I've really liking my Urban Decay Primer Potion. I'm liking it so much that when Ulta gave me 100 points (I don't know why, it just came in an e-mail!) which is a $3 gift card essentially I decided to pick some up. I bought the travel size for $12 (with coupon in was $9) which contains 6 ml of product. I figured I'd get about a year of use with this one because I'm only half way through my first pouch of sampler! Even with the amount of waste involved in  the foil packet I'm only half way through after about a month's worth of use! So, even though the sampler says each packet is good for a week, if you are careful and only use a small amount of product you should get over a month!
