I just got the bump in points to $2000 also. But I bought my 2011 1LT V6 Equinox this time last January, so I'm not really looking to buy another new car just yet.
The deal adds another $1000 in Loyalty cash, but only for Avalanche, Corvette, Silverado, Sierra, and all Caddys.
Loyalty cash is only $250 for Equinox, Sonic, Volt, Verano, and Terrain.
Everything else is $500 in Loyalty cash.
Good through February 29th, 2012.
You STILL cannot use GM Earnings to purchase a Volt (or Camaro ZL1).
For Loyalty cash you must prove you own or lease a '99 or newer GM vehicle.
Ad says that "Bonus Earnings can be used above GM Card program limits". HA! I've been a member since '95 and can accrue a maximum of $3500 in Earnings, but I've never been offered "Bonus Earnings" that, when added to my current earnings, exceeded $2000-$2500. I think once your Earnings pass a certain threshold, they stop sending you the "Bonus Earnings" offers.
