and searched "43R1962" on Google and one of the sponsored ads at the top come up with the prices in the ads I don't know how they do that? as all the items from that advertiser have the prices in there ads and they can't put the prices for all the items manually ?

Affiliates often do this with merchants' product feeds. They have a file that contains the product name, description, price and URL. These "pieces" can easily be combined into unlimited number of ads, without a great deal of time.
Adwords API could do this automatically. Some advertisers hook it up to their product database, so when there is a price change or inventory shortage, changes are made to the ads in near real time...
