Jungle shopping

Do you ever think it's terribly strange when you find out that Amazon.com doesn't carry a particular item? I do, and I didn't really realize it until now. I just expect that Amazon will have each and every thing that I could possibly want to buy. I may not want to buy it from them, but I just expect them to know how big it is, the retail price, who makes it, and so forth. I'm sure that there's a way that they can take advantage of that fact. Maybe they already are.
