Well from someone else that basically lives here at WGT... I have to say I couldn't agree more.
I use the 10c spinners as I play alot and barring any water or lost balls i burn about 3 a day.
I have 50 an 90c balls that i only use for special games. But if cheaper to buy in bulk more games may fall into the special group as i wouldn't care about ball cost per game quite as much.
Basically if a discount of sorts was in play player may be a lil more risky or wasteful with the balls. And that seems like a profitable angle for WGT.
Don't get me wrong I love the game an 95 percent of how they do it. Since I live here sucking up bandwidth buying clubs and balls is my way of paying rent.. lol.
I buy my balls 10 pks at a time. Buy 9 get 1 free would be a nice "thanks for playing so much" from WGT.
