It will be awesome if there is a second-hand market (flea market) where players can sell & buy their clubs, balls, etc. among themselves.
This can be another cash cow for WGT if they charge, for instance, 5% commission fee for each transaction.
Some might say this could be abused by multi-accounters, but quite on the contrary, WGT will be able to detect any abnormal, suspicious transactions and identify the multis.
This will increase the sales of pro shop items as players will purchase equipment with less pressure or burdens. They buy something, try it for a certain period of time and if they don't like it, they know where to go with it.
It's good for both WGT and players.
