Charity Auctions

The items you see at a GPS Charity Auction are donated by members of the community and we’d like to thank everyone for their generous support. We use these funds to support the programs and mission of GPS. We also look for donations of time from volunteers who can help keep inventory, prepare for conventions, and set-up/staff/tear-down at the events themselves. Generally, we hold 3-4 charity auctions at partner events a year.

Would you like to partner with us and host our charity auction? Please contact us a minimum of 6 months prior to your event.


  • We accept donations of auction items year round – at GPS events, at convention planning meetings we have representatives at, by appointment at our center Event Horizon in Northeast Minneapolis, or by arrangement to deliver to the convention you are attending.
  • We will try to match items donated to conventions based on a convention’s genre or theme for that year, so we will take all the geeky things – all genres, all media formats, all types of collectibles, etc. Please keep in mind – if you are delivering to a convention, while we will try to fit your item in that year we are constrained by space and time so cannot guarantee that your donation will be in that particular auction.

Email for questions, to volunteer, or to arrange a donation delivery.

We also have a form that you can fill in with the information about your donations. This helps us catalog/categorize your donations.


Before a convention we pack up items selected for the auction, create bid sheets, print signs. At the con we set up the tables the day before (no membership is needed to volunteer before the conventions starts). During the con we need people to monitor the tables, register bidders, and answer questions about the auction. Sunday we need runners to help gather items up for winners as they come to pay and people to help pack up everything else. Please email  if you are interested in helping.
