they were a part of clixgalore.com before but now they're not listed a merchant, im gonna looked for it elsewhere also nothing found about pricegrabber.com on reporting. net.
Update:
http://www.pricegrabber.com/home_help.php?keyword=affiliate+program
all i can see there is that they reward individuals to rate/vote/review their merchant products and no affiliate partnership/programs mentioned but the merchant partnership is a good paid one to make money as well. HTH
pls. wait while i update this post.
