I've found some useful tools, products, and equipment at a great price on a couple of charity auction sites. Over the years I've bid on and won raised garden beds, a self-propelled lawn mower, a watering system, and more. Sometimes you need to live within a certain amount of miles to bid on the item, and sometimes the owner is happy to mail it anywhere. I save money while supporting charity so it's win-win. My favorite site at the moment is biddingforgood.com. Have you found any useful online auctions that support charity?
