- 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.

How to Participate
1. eBay for Charity
The G4G Auction is primarily held on eBay for Charity where 100% of auction proceeds will be donated to the G4G Foundation. The eBay auction features a wide variety of physical items (games, puzzles, art, jewelry, books, and more!) as well as services and virtual experiences (mentoring, magical performances, and tours). Functioning in the same way as the original eBay marketplace, eBay for Charity allows us to efficiently sell a wide range of donated items through their platform.
PLEASE NOTE: G4G does not offer appraisal services; auction item values are estimates provided by the item donor. These values have not been independently verified by G4G.
2. Partner Sites
In tandem with the eBay auction, G4G has partnered with a few e-commerce websites who have graciously agreed to offer a donation of 15% of gross sales from Sunday, October 23 through Sunday, October 30 (the same days as our auction) to the G4G Foundation.
