There are many different ways to earn a little extra cash from home using the Internet, Online surveys can be a good method but some of the sites on offer can be very poor so it is best to do a little research before you start, 

I have tried a few different ones lately and had some mixed results, Some of the Internet survey sites work on a points system and others will offer cash,  However in both cases you will have to reach a certain minimum amount before you can cash your earnings in, One of the draw backs with survey sites is that it can be time consuming and will seem like slow progress, In some cases you may be given a survey to start and before long you may get told that you do not meet the right criteria, when this happens the survey will end and you will not get any rewards, This is very frustrating but if you keep your profiles up to date you will soon be given correct surveys and will soon start earning,

At the moment I have found 2 that I would recommend,

The first is: Lightspeed Panel, This site offers a good amount of points for each survey and you will be able to turn them in to pay pal vouchers instantly,

Secondly : GlobalTestMarket, This site offers points for cash, but you will need to get 1000 points before you can cash in, however it does not take that long,

I hope these sites work for you, If you know of any others feel free to post a comment
