I noticed Google Checkout is now the system of choice, is Paypal no longer availible?
You can still use PayPal, just scroll down on the purchases page.
Also, regarding the radar upgrades, might I suggest instead of being allowed to purchase a specific level, that you be allowed to purchase a certain number of upgrades? The reason I ask is that at $39.95, the Level 4 Radar upgrade represents a MUCH better value for someone with a level 0 radar than it does for someone who has already paid to get moves to earn the MD for the upgrades. Here the newbie is paying $10/upgrade where someone with a level 2 would be paying $20/upgrade. The way I suggest is that you allow a single level of radar to be upgraded at 8.95. This way someone just starting will pay the same amount they would now to read level 4, but those who already have say level 2.
Just something for you to consider.
I like this idea. As soon as I have time I'll make some changes to the way upgrades are purchased.
