Visit bidding sites like eBay and bid for your best offer. You may even end up buying the least used pair of Jordans for a very meagre sum of money. But again, beware of frauds. Make sure that you see the actual photograph of the product you are bidding for. Do not start offering your bid for a product that has no photograph. Looking at the product photograph would let you decide its top bid.
Another alternative is to place an Ad in the newspaper. You will be stunned to see how many people reply to that for no one will be ready to give away their Jordans unless they get some cash for it.
In that case, you can be choosy and choose the best of all that comes your way.
