If you tell them you are not sure they may know for sure, one of the biggest reasons we all hate losing our LHSs is that the knowledge they have and the advice that they give can be invaluable. If they do not know, they can make a judgement call on it based on the likelihood of you taking it, the likelihood of them selling it on if you don't, and what it is worth to keep you happy.
