Raffle

From RoboWiki

In the fall we do a raffle. We'll sell tickets for $5 which get people an entry into our raffle for a new laptop computer.

We set up dates to go sell tickets outside supermarkets, and around school and to relatives. It brings in between $1000 and $2500 depending on how many tickets we sell.

We pull the winning ticket in December and send the winner their new laptop.
