At least two ads in the "Win jewels" section of the site don't offer the payouts they promise:
Blue Buffalo
Complete survey and video view; then click through site. No purchase necessary.(I tried this several times over, and never received a reward.) (Please note I wasn't trying to receive multiple rewards for the same action, I was trying the ad again at a later time after not receiving the reward, just in case something went wrong, but I've done so at least three times now without success.)
Hepatitis C Social
Learn about Hepatitis C. Submit your e-mail to receive rewards.(Tried this twice, the second time I even registered at the site; no rewards.)
In addition, some ads lead to blank pages, nonfunctioning pages (for example, a couple of game links, like the "Feed Me" game, just bring up a spinning icon and never load), or to pages that have nothing whatsoever to do with the ad described in the "Win jewels" section.
Examples of the latter are:
Shift Work Disorder
Click banner, register with valid information, download savings card...(There's no banner to click. I experienced something similar with another ad that mentioned clicking to "find doctors," yet there was no such link on the site.)
and
Simple Heart Test
Register with valid contact information. No purchase required.
Family Dollar
Print a coupon. No purchase necessary.Those two, plus other ads, forward you to "http://apps.xenrg.com/" and "http://vc2shop.com/"; the URL changes every so often but is usually those two. Those aren't the ads advertised, nor do they allow you to perform the steps necessary to earn a reward.
And this site
Fishpoll--How Does Your Self-Image Rank?
Take the poll, submit valid contact details and continue to the results page. No purchase required. You may skip sponsored offers....is just misleading--it keeps bringing you to page after page of sponsored offers, and never lets you proceed to the results page.
Sorry to sound so picky but I just thought I'd point some of these out.
I do appreciate the few ads which did provide promised payouts.
