It's a $1000 (usually) rebate to be applied towards the purchase of a new Chevrolet Camaro. Members get it by navigating through the Chevy home page and building a camaro. It has to be applied by a certain date. I think it is only activated at certain times of the month, and maybe even for certain models and zip codes. I got mine using another zip code and another model camaro, but once it pops up, you can put in your real addy and model and trim.
Do a search...there are a couple of good threads and I think even a member that can get one on consignment! Good luck.
