I have done some research on these sites that offer you free items for completing a set number of offers. I.E http://www.desktopcomputer4free.com/. I do know that (most) of them technically do work, seeing your getting a free item for no money through the “Affiliate Marketing” method. But i am not really sure of how long it would take to finish completing all these necessary offers to get your free item. I am willing to put in the time. I know different items take different times to gain enough credits, but i would like a ballpark estimate.
