A lot of depends on where you live/how rural you are. There are lots of people who will sell things on ebay on consignment or other options. You might try contacting a local estate sales place and ask if they have options or know someone.
On my local (Illinois) shop hop, we stopped at one place that primarily received their items from estate sales or store closings.
We don't have it here, but back in Seattle, I loved MaxSold -- sort of a hybrid between Craig's list and ebay. The items are placed for auction, cash is received through the service, and then the items are picked up by buyers.
