100% of the proceeds from Bidsquare Cares go to benefit charity: water, with package values starting from as low as $25.

"Once again it is that time of year when we are afforded the opportunity through the annual Bidsquare Cares charity event to take a step outside of our archetypal auction world and work with our colleagues to help those in need in developing areas of the world." says Ron Pook, one of Bidsquare's founding partners. "Thank you to all those who have joined to make this happen."

Bidding is now live and closes on December 4 at 12:00PM EST.
