Ok,
So, the Google Affiliate program generally pays about 8% of sales....better than Amazon, but....
So far, of about 10 data points that I've found, if you can find the same offer direct through the company or other affiliate marketer, you get a lot more money as an affiliate...
One example is the Chef Basket from AsSeenOnTV:
Google Would pay men 8% of the sales price of $14.95
Peerfly would pay triple+ this
If you were signed up with AsSeenOnTV affiliates prior to them "Going Google" you would make about a buck more than PeerFly's payout (which isn't bad...)

I haven't purchased this offer, but assume there's a downstream for refills, etc that the actual company makes their real money on...

Anyone else seen the same thing. I've basically resorted to just using the Google affiliate offer if I just plain can't find another...

With many folks on Amazon that buy multiple items, its even almost better to go that route IMO than Google on the chance they buy another item or two....
Cheers,
James
