Help your foursome out with four mulligans (one for each player on the team), and 3 yards of Gimme String! (Once on the green, measure the distance from the ball to the hole with Gimme String. If it's within the string and you want to use it, the putt is good. Once a length of string is used, it must be cut off and discarded; you may continue to use what's left. When the string is all gone, you and your putter are on your own.) 

At a cost of only $20/player, can you afford not to have the same edge taken by most other teams?
