price fixing a hole
Pricing on Amazon is weird. Ever since I bought my new girlfriend camera I've been watching the price every couple of days. Right after I bought it, Nikon announced a new model at the next price step above my D40. There was some speculation on the interwebs that that would cause the price of the D40 to drop. I kept an eye on Amazon so that I could cash in on the 30-day price protection guarantee if need be. At one point it was available for about $10 less than what I paid. I sent in a request for price-protection, and by the time they fulfilled it the listed price had jumped back up so that it was a mere $0.41 less than what I paid. I gladly took that refund all the way to the bank!

Since then the price has fluctuated a little, mostly upwards (that I've seen anyway). For most of the 30 days it was hovering around $10 more than I paid, and as of this morning it was around $20 more than I paid. However, this morning, if you bought both the camera and an extra battery you could get the combined lot for about $15 less than I paid! This, 31 days after my purchase, and thus, out of price-guarantee territory. I hope that nobody bought it today and failed to see the bundle. Even if you don't need the extra battery (which, really, you don't because it lasts upwards of 500 shots) you save a decent amount of money by just dumping it on eBay.

I'd be very interested to learn exactly how Amazon sets their prices for an item at any given time. I'm sure that it's a closely guarded secret. I've seen reports in the past that logged-in users sometimes get different prices vs. non-logged in users browsing at the exact same time. This is actually pretty brilliant as Amazon has a huge database of buying preferences for its millions of customers and could theoretically alter prices one way or the other on items it thinks you are likely to purchase. My economics major brain is fascinated. Every 10 years or so I have to pretend that I actually remember something from my college education.
