The original MSRP contribution was written for osCommerce MS2. Some code got changed beginning with RC1 that has made it difficult for people to figure out how to install this contribution. I have therefore updated the instuction files to account for the changes in the osCommerce Release Candidates so if you are modifying an install of osCommerce version RC1 or later use these instructions and not the original contribution. I've also tweaked the output so that both the savings amount and the percentage savings are displayed.
