So I recently renewed a domain+hosting plan and I was given a free Google AdWords credit code. I have no use for it at the moment. Does it have any sell value?
your subject states adsense but your post says adwords?
if it is a straight up $100 dollars than it has value but if it is one of those were you have to spend $25-$50 to activate than probably not because you can get those for free from time to time.
