Points for Free Samples

I'm fairly new and have noticed and tried to earn SB by clicking on a couple Free Samples offers. I finally gave up after over 10 minutes of clicking on pages that seem to take you to other pages with another set of endless questions. The samples aren't necessary but the points are nice. My question is, is there a secret to navigating through a Free Sample offer or going through a hundred sites and pages seems to be the norm and they should be avoided.
