Here (and reproduced below) is what Wells Fargo Rewards displays when you try to buy a "$250 Hertz Certificate". Emphasis mine. I turned my monitor over and over trying to find the reverse face of the voucher, and could not. So this display is MEANINGLESS! And there's significant information missing that affects whether this certificate is a good deal or not. Will there be a redemption limit on the face of the voucher I get? When will it expire? Will it be transferrable? The site won't say.
