Gordon,

I've used "The Split" strategy at my site, MyLittleWhiteMug.com, with tremendous results.

I offer my product by giving 3 options to buy, along with 3 different package offers. I've also used the strategy to show the best first.

But I've taken it a step further. I have a hidden page and each package is still offered with a greater discount for the buyer. But if they want the offers from this page they are going to have to do some detective work to receive the reward.

I would also add that studying Underhill, Brennan and Linstrom's research takes "The Split" to a whole different level.
