This sample is a bit different then most of the samples I usually post but I felt it was worth the time it took to complete.
This is for a year's subscription of Popular Science, Ode, or the current magazine special.
All you do is go to the site, select the magazine, (sometimes there are other magazines to chose from), then watch a few 30 sec-3 min ads which vary on a point system based on commercial length. It takes from 20-30 points to get the subscriptions.
You can open it in a new window/tab, mute it, and let it play while you do other things. I picked the longer videos to get the points more easily.
Be sure to catch the end of the clip where you have to enter in the verification code within 30 seconds to get the points credited to you, otherwise you have to watch it again.
After you earn 5 points it asks for your mailing info.
This took me about 15 minutes of play time and about 1 minute of actual typing and clicking.
It takes 6-8 weeks to have them sent out to you.
