Enter to win tickets to the US Open and you'll also receive by email a certificate good for an additional $1000 of a new Lexus. Certificate expires 12/31/17. This is IN ADDITION to any and all rebates and whatever you negotiate!
The fine print says:
Customer Instructions: Offer valid for the person named above who purchases, finances or leases a new Lexus at a participating Lexus dealer. Offer void where prohibited by law. Negotiate your best deal first, and then give the $1,000 certificate to your dealer, who will apply the discount toward the down payment on a finance contract, or toward the amount due at lease signing, or toward the capitalized cost reduction on a lease. This certificate must be presented to your dealer at the time of purchase to be honored....
