At a local club I was a member of years ago I set up a table with three items on it for a 'Silent Auction' for fund raising .
I put a clip board in front of each item and started the auction at .99 cents. The bids went up in $2.00 increments (that was more fair because some of the women had deep pockets and could easily have outbid everyone else and ruined the fun of it) and you could come back and write your name down as often as you wanted and you HAD to be present ( in the building to hear your name called) at the end of the two hour auction to win.
What a blast that was! Everyone loved walking by the tables and writing down their name and I set the end time for when the meeting would be over. Two hours later and there were about 60 signatures on all three items. We also got a lot more for the items. I donated the money generated to the club library. Maybe you could try something like this?
