Put them where the games are...
Then, EVERTIME someone walks down THAT isle, a salesperson should, after being trained on the proper sales technique, approach everyone who even looks at a console/game/remote.
The sell is so easy...it actually could sell itself...
One Game $50...
5 games is $250 which is a yearly 6 out plan..
You get so much more for your money that way.
Then downsell to the $8.99 plan if necessary.
really simple.
