I'm thinking of getting Vue 4 or maybe 5.

I've d/l'd both and tried them out. It looks like if I buy 4, then upgrade to 5, then I will save more money then just buying 5.
Am I thinking this out correctly?

Vue 5 $249.00

Vue 4 $69.00
Vue 4 to 5 upgrade 149.00
This comes out to 218.00

And there is another one that says: Applicable to customers who bought Vue d'Esprit 4 after September 15th, 2003.
for 129.00

This totals only 198.00

Mover is mover no matter what - $99.00

Is there no way to call these people?
