Thanks Sarah for pointing this out to me!!
There’s a tool called RSStalker that lets you track price changes on Amazon by RSS. You can have feeds for your entire wishlist or a specific item.
Also, from the RSStalker site:
Amazon.com doesn’t advertise it, but they have a 30 day price drop policy. If you bought something from them and they lower the price within 30 days, just fill out a form and they’ll refund you the difference.
So, armed with the knowledge of these 2 things, you can now save yourself some money – or at least get some money back!! Awesome!
