Is it that time of the month?

The "new vs. used" thread made me think about all the gear I've bought/sold in the last 4 years or so & I just had a look at my feedback & noticed in the past three years, I've only missed 4 months where I didn't have at least one transaction. As I look at my modest but decent system, I can't help but think how truly obsessive this has become. Not wanting this to denigrate into a gear vs. music thread, I'll say up front I enjoy both equally, as evidenced by my involvement in pro audio and that I still enjoy having the house & the sweet spot all to myself. (when available)

So, the question is, do you feel compelled to buy something because of one of the following (or other) reasons?

1) haven't bought anything for awhile
2) extra cash is burning a hole in your pocket
3) too good a deal to pass up
4) need to keep a balance on your credit card
5) it just sorta "happened"

I've taken these 5 from personal experience and the last purchase, which was well over 2 days ago, was #3.
