For those that list items on Ebay for sale, you can choose the as a non profit donation and donate between 5% and 100% to the club or any one of hundreds of other NP's.

Not only will you be supporting the club, its great advertisment as it tells everyone who sees your auctions about the club and that you are a supporter.
