I have 2 full size beds with box spings and matress, one sofa in good conditions and need to sell them. Looking for a store in Miami, Florida to sell them at, do not want to post anything online, do not like craigslist or eBay where can I find a store?

Find a used furniture store to take them but don't expect to get a good price for them. No one wants used mattresses nowadays because of the bedbug epidemic. Your best bet is the town dump. But then it would cost to get them there.
