For a fun experience, try this free website. You buy and sell your wares, much like an online garage sale in the tradition of olde time barter and swap. NO MONEY. Yes, it is free to list and costs no money to buy.
The site works on credits. They gift you a few credits to get you started. You earn more credits by various means, but primarily you list something to 'sell' for more credits. It is the good old swap and barter system. Easy to sign up, they ask NO personal information. All transactions are between the trading partners.
One man's junk is definitely another man's treasure. Thousands of items to hunt and peck through. Some amazing deals. VERY LOW risk.
