I wonder what the average gift certificate/gift card utilization rate is? I'm sure it varies by store, but I bet that gift certificates are pretty profitable. I keep pretty good track of things, and I know that I've got a fistful of gift certificates that I haven't used. Does anyone have any hard data? I bet that the percentage of gift certificate value used is less than 80%, which makes the sale of such certificates very profitable. (And even moreso, since the value of the certificates don't adjust for inflation.)
