urban decay primer potion is only $14 or $16. save your money on the cheaper ones, and just wait until you can afford the UDPP. ulta's primer is a piece of shit, IMO, i ended up returning it, and l'oreal de-crease was similarly disappointing. it gets to a point where you waste so much money trying to find cheaper alternatives, and not succeeding, that you might as well have bought the original product in the first place. plus, UDPP lasts a loooooong time, because you use so little on each lid.
