Very nearly at the beginning of our existence as a weblog, we posted a link to Amazon Credits You, a site that helps you watch out for potential savings if Amazon drops their price on an item within the 30-day price guarantee window. We went back today to dig up the name of the site so we could punch in some numbers (see, even we use our tips; we aren’t totally phoning it in) and discovered the site has been changed to Refund Please.
