I purchased a 2005 Trailblazer and was able to combine GSU and GM Card earnings. Did the same thing in 2006 with my Impalla. I worked hard to build my points back up and went to the dealership for a new Trailblazer and was advised the two can no longer be used together. Was anyone notified of this?
You haven't been able to combine them for years....I think 02 or 03 but they may have just sold under invoice and gave you the GM Card money.....Or they really screwed up
