There is someone on my shopping list who wants a iPod Nano. I figured this would be a great item to use to compare the proliferation of shopping engines that are out there. I have traditionally been a big Froogle user. It’s simple and straightforward but comprehensive, and I feel like I am finding the lowest prices on things I’m shopping for. But lately, there have been more merchants who are gaming the system (call it Shopping Engine Optimization). I click on the great price that they have on an item, and show up at their site only to learn that the item is now $200 more. I’m not sure if its cloaking or not, but it decreases the value of the shopping engine to me.
