Online Auction Fundraiser

  • When:   Sunday, October 23 through Sunday, October 30, 2022
  • Timing:  Auction items will open for bidding between 10am and 11am PT and each individual auction item will close at the same time one week later. Individual auction items’ opening/closing times will be intentionally staggered to allow participants to easily bid on multiple items.
  • Where: eBay for Charity and Partner Sites (see details below).
  • What: 
    • A wide variety of items have been donated that we expect will spark the imaginations of the G4G community and like-minded friends. These items will be posted for auction via eBay for Charity where 100% of proceeds will go to support the G4G Foundation.
    • At the same time, a few e-commerce websites have partnered with G4G to donate 15% of gross sales from this week.
  • What kinds of items will be in the auction?
    • Puzzles & Games, Artwork & Jewelry, Mentoring & Tutoring, Performances, Books & Magazines, Services, and Tours


  • Can I donate an item/service to be auctioned?
    • Not for this auction. But let us know if you want to donate something for a future auction.
  • How does shipping work?
    • For many eBay auction items, winning bidders will be responsible for covering shipping costs, which will be paid as part of the eBay purchase. Winning bidders may also be invoiced separately via PayPal after the auction closes for additional shipping insurance coverage.
    • For Partner Sites, please contact the site owner for shipping details.
  • Is my purchase tax deductible?
    • If you donate an item to the G4G auction, usually the fair market value of your item(s) is tax deductible. We advise you to consult a tax advisor.
    • If you bid on an item on G4G’s eBay for Charity site, only the portion of the bid ABOVE the fair market value is tax deductible.
    • If you purchase an item on one of our Partner Sites below, your purchase is NOT tax deductible. However, 15% of your purchase will be donated to the G4G Foundation.
    • G4G will provide official tax deduction letters to all eBay auction participants (donors & bidders) after the auction concludes.
    • Consult your tax advisor for your specific circumstances.
