Going through the older discount engine file and re-vamping the code. We need this file to use a new database column and keep working while we work on the new one. Going through the older file, line by line, and making changes. Small disclaimer, I had to physically skip certain sections and pieces. It was stuff that I don't know, mostly dealing with the style that it was written in. Anything that I could, I changed it to our normal (my normal) standard of code.
