Amazon Certificates

I belong to a few differnt online forums many of which offer Amazon certificates as payment. The online forums do not require a lot of work just usually answering a few questions per week, most of them offer ten dollar monthly Amazon incentives in lieu of cash. I was just able to get an ipod alarm clock with my certificates and have gotten other items in the past such as an ipod shuffle, a blender, electric toothbrush and dog grooming products. I think these sites are good because it is easy to participate and earning the certificates is nice. I would for opportunites to join these communities as the compenstation is more than fair for most of them.
