In case anyone hasn't seen the deals being offered by DRF, here they are.
The only negative is that you can't buy the pps by themselves. You're forced to get the package including the Players' Guide and Gameplan. The Players' Guide is usually good info, but the Gameplan nonsense is a joke. However, it still brings the Formulator cost down to $2.25 a card which is 1/2 price a typical card. A fantastic deal considering the many features Formulator provides. Good luck this Summer!
