I see that I received a credit from BigFish games in the amount of $2.00. The only purchase that I've made was $9.99 for a game for my kids. According to the link, BFG only credits 5%, not the 20% I received. I'm not complaining...but I am wondering if my kids have been doing a little ordering that I am not aware of. I looked in my order history and only the one game is listed so I'm not sure why I got the "bonus".

Any ideas?
