Confused, also if you are good with humor, you might play upon the car sale example. When offered a bid, be gracious and say "Thank you, but, hey, I need a bit of time and to kick a few other tires first! But I will definitely give it careful consideration". This may work if you can pull it off. If they nevertheless push you for a hasty decision, there is nothing wrong with saying, "Thanks, but I am just not ready yet for a bid."
