I know that BLT has $8.00 off per point for 50 - 99 points (so $104). I believe that AKV is $10.00 off per point for that same level of points. There are no incentives off the $112.00 for contracts smaller than 50.
But, the BLT incentive is rumored to go away on June 15th. Not sure about the others.
I am doing another 50 point BLT add on and will be starting the process this week. This way, if the incentives go away, I am locked in. And, if new ones are announced a few weeks later, I should still be in process and will be able to switch.
Good luck!
