What are sports bonus codes, and should I use them?

Sports bonus codes are unique identifiers some bookies use to keep track of the bonuses they use. They also use them to help identify which bonuses generate the most interest. They are not a necessity today. Most bookmakers have moved on to methods of tracking bonuses that allow them to do everything automatically. However, there are still quite a few who want to give you that exclusive experience. I personally think bonus codes are still fun.
