The only ones I've ever seen are paper ones printed by Dollar on glossy brochure-type paper to hand out in person at conventions, etc.

The only other upgrade certificate I've ever seen are for government renters:

(They will require government ID before honoring the coupon.)

In both cases, they are only available up to a maximum of the Premium or Minivan classes. I have never seen an upgrade coupon valid for any SUV.

Dollar promo codes and corporate discount codes do not provide upgrade benefits. Dollar's computer system cannot handle those types of requests electronically.
