Most people on the Internet who are looking for good deals normally choose to shop with traditional retailers or they may place a bid at their favorite auction website. There is another way to land a fantastic deal and that doesn't requireperson to pay an arm and a leg after the deal is done. Consider the art of swapping your old or unwanted items you have for unwanted items other people have for example.

This article was inspired after following the bartering (swapping) skills of a man named Kyle MacDonald and his website “One Red Paperclip". Kyle, Swapped his self from one trade to another, until he had himself his very own house. Amazingly, he managed to swap himself to a house in only fourteen trades.
Now, I am not suggesting that anyone can do what Kyle MacDonald did, but if you never try, then you will never know. Even if your idea isn't so grand as swapping until you achieve something big, it is cheaper than buying new or bidding in an auction. You can still swap your old things for the things that you want and only be responsible for paying the cost of shipping the things you have agreed to swap with another member(s).
This list isn't a Top 10 list, but if it were, then I would suspect that this list would look pretty much the same as I have it right now. So, enjoy!

Fashion and Cosmetics
Swap Style
Swapstyle.com describes itself as “an online fashion swap party where you can swap, sell and buy fashion, accessories, cosmetics, shoes and lots more with people from all around the world at any time, day or night”. This is a fantastic idea in my opinion, because it can save its members a lot of money on the name brand fashions and cosmetics that are normally purchased at retailers at high markups. Members can also participate in forums and discuss the latest fashion trends, sales and/or whatever comes to your mind at the time. Members are only responsible for paying the actual shipping costs associated with the items that they have traded or sold and the other members are responsible for paying for the actual shipping of the things that they agreed to swap with you. Membership is free and required.
