CTBIDS grew from an idea over 10 years ago by Caring Transitions owners across the country. These owners are carefully managing the treasures and everyday household items for their clients as they downsize or transition to new homes. These items have quality, value, and a history that are a perfect fit for someone else. Our mission was to create a platform where these estate sales are brought to you online. Instead of set pricing, bidding starts at $1. This process allows our bidders to find unique and everyday treasures for a great value. In addition, the repurposing of these belongings will have a positive and lasting impact on the world we all share. CTBIDS is powered by Caring Transitions. Established in 2006, Caring Transitions is the nation’s largest and most trusted organization specializing in downsizing, relocation, estate sales, decluttering, home cleanouts, online auctions, and other services.
