I forgot to mention in my original post that I signed up for click and ship with the USPS((thanks
@poisondartfrog), this reduced the cost of mailing to $8.80 per player. As I was getting packages ready today I realized that I didn't have enough singles to send everyone back their $2 change. I started to keep a list but gave up towards the end, I was pushing it close and possibly going to miss post office.
If you receive your package and the $2 change is not in there, you can message me and I will send it out in a regular envelope.
