This goes beyond just the 7 day price match and return policy. This topic is actually very timely. I've been buying some things on Amazon lately. The price fluctuations make me feel as if I'm buying stock. Product should not be changing/bouncing around all over the place. One item I was going to buy was at $37 for a couple of weeks. I finally get around to wanting to buy it. It jumps to $49.95. I watch the item for a few days. Then it drops again to $37. Should have pulled the trigger then but I was heading to bed and was going to order in the morning. A mere few hours later and the price jumps back up to $49.95. Really?
I found a site which tracks pricing history for items on Amazon.
www.camelcamelcamel.com You just drop the URL into the search field and it spits out the price history for the item for I think the past year. You'd be surprised by how much pricing swings happen. Another item I was watching jumped from $167 to $219.
