need an ebay/amazon bot

that will scrape the items that have the biggest variance in price from one site to the other.
for instance there was a product i saw which was a novelty item pertaining to a Marvel comics character.
it was like $20 on ebay and like $220 on amazon.
need a bot that will provide a report showing these items.
pm me please if you can do this

I would also be interested in a similier bot!

I don't think it's possible, both sites have different way to work. I guess we can only check title and compare. there is not other way I guess..

though if anyone have more detail about that logic.. welcome
