upgrading my phone with bell

I currently have the old chocolate phone, and I want to upgrade to the LG Voyager.
I've called bell, and I'm very confused.

I have a $50 credit on this phone now, and apparently I get $100 in july (They keep changing the date I get my credits!!?!)

Anyway. If I want to upgrade to the LG Voyager, does that mean i need to sign another 3 year contract, and then pay the FULL price of the phone? Because the price of the phone without a contract is nearly $400
and if I'm signing a contract again, shouldn't I get it for that price instead? Please explain!

The credit that you are eligible for is a reduction on the retail price of a new piece of hardware.

And yes, a contract renewal would be required.
