In 2004 I purchased a year long practice card from Strikezone myself. 400 dollars was the price. The option was to buy a 3 month, 6 month, or 12 month practice card, with various prizes. I found this to be excellent value, and a lot of fun also. The practice card was very worthwhile to me. It helped me lift my game and all-in-all improve on areas I was struggling with.
The value the people get out of this card made them want to keep buying one.
Not only do the centres that sell them get incentives and bonuses, etc. from this card, but also the bowlers. Without the practice card, I am sure I would have struggled a heck of a lot. The card really helped me improve my game just that bit more.
I'm sure that the bowlers who bought the cards, and also the majority of bowlers who have seen what the card has on offer will agree that it is very worthwhile and worth the money. 7 games max. with the choice of maybe having 3 or 4 games, then coming back later on and bowling the rest, or bowling the full 7. The card is a great opportunity to practice those pesky 7s and 10s, different lines, sparing different pins, or even practicing with anything you may be struggling with...
That is excellent value.
