I have around 50$ to invest into a website, What would you reccomend? Also, I have all of these: http://www.the-cash-magnet.com/productdetails.htm
$50 isn't a lot of money. You can barely pay for a 1-year hosting plan with this money. I would recommend that you start a free blog at blogger.com and use this money to buy links.
As ablaye said, $50 isn't a lot and their recommendation is a good one. Or, look into putting your money in the bank. Seriously. Something like ING, which has no minimum and 4.3% apr.
