Question about something I have on e-bay?

I am really trying to make some money right now, I found a pair of crystal goblets hanging around my house and put them on e-bay along with some other stuff. As my auction was ending, I got a message from a crystal store telling me I had them listed incorrectly, and that they are worth about three times what they sold for- and that I should put them up for a buy it now under their correct name and get much, much, more. Can I refund the winner’s money with a nice note and relist? I hate to have someone recognise them and slap them right back on there, just because I didn’t bother to research my item, and make several hundred dollars. What would you do?
