Mechanical Turk is an Amazon owned site which pays you for carrying out tasks such as article writing, fact checking, web site reviews etc. Some of the work isn't that well paid but you can pick up higher paying work such as article writing and the money soon adds up.
This is one of the highest and quickest earners I've come across and it's well worth a look. If you ar e based in the US you can have your earning paid in to your bank account, anywhere else you have to have gift vouchers.
If you want to turn your vouchers in to cash it's simple enough to buy new products from Amazon and then sell them on eBay. If you choose your stock well, you can make extra money that way.
