What is your shipping rates like? I know for myself and friends, that is one of our biggest reasons for abandonment once putting things in the cart. Are there other surprises they discover once they get to the check-out area? (e.g. delivery time)
Definitely don't get rid of (and if possible not move) content that anyone is coming in thru or linking to. There is no guarantee G will consider the new page as valuable as the old one. Just try harder to monetize it. There is nothing that says you can't put Adsense (or affiliates - which might be one way to determine if you are making sells for someone else, just not yourself) on it where it is, and STILL embed your own strong recommendations to buy your own.
If you're sure they are coming there looking to BUY, versus just, say, finding out "what the heck impressionist art IS", then put on your used-car-salesman's hat (no offense intended to used car salesmen, they are an effective, hard working... lot) and convince them right on the info page all the reasons WHY yours is a better value than all others. If yours AREN'T the best value, then consider linking to an affiliate you truly, personally believe is the best and do the same sales talk.
