I try to limit myself to one TRANSACTION a month, no specified bottle-count or preordained monetary ceiling. That way if I think I want something, I have to buy it on the day I buy everything else for the month. A number of times it has happened that Ive been on Scentiments etc. and said to myself " thats waaaay too many bottles". I find it helps to have your total monthly expendtures listed together on a page before your eyes. Then If I decide I want something new a week later, i have to wait until next month. This delay also helps weed out those frags that I really want to acquire from those that are a passing fancy because you guys are all raving about its charms or someone got bitten at work because of it.
