changing from auction to Buy It Now - your advice please

[Finbar]

One watcher who made a bid on my item. Now contacted me to ask if I will do a Buy It Now. One day to go on auction.Never been asked before.
Is this ok?
What would you advise?

you can't do a buy it now once there's a bid.

you can end the auction early accepting their bid at its current level, or let the auction run and see if anyone else bids.

if you do want to add a buy it now you can cancel their bid and add it. But if you don't want to don't, it is up to you.
