FAQ
- Can I donate an item 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.
- 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.
- Consult your tax advisor for your specific circumstances.
