Dear Amazon
I recall in my Econ 101 class some interesting material explaining the nature of supplementary versus complementary goods. Primarily the course material was about how as the price of a good goes down, causing more purchases at the new higher level of demand, the demand for complementary goods—things that are used with the first thing—goes up, while demand for supplementary goods—things that are used instead of the first thing—goes down. As a modern internet business, I would expect you might be familiar with the idea, as more businesses plan around giving away goods to make money selling their complements.
Please review.

So much more eloquent than my response of "Amazon, WTF?" when it happens to me.
free to gift to anyone. Not a bad deal!
