First off, happy new year. Second, thanks for the reply.

I did in fact try many. Not all of them but the ones I saw were posted as the best ones. And all of the coupon codes failed because my reservation didn't meet the criteria. As for the AWD codes, maybe it was just my bad luck but I didn't find any that were cheaper than my generic Avis First rate.

If that's as good as it gets, then so be it. But I was hoping someone might have a code unique to SFO or some other qualifier, if that sort of thing even exists.

Thanks again.
