Bananas was buying a book, once equipped with an isbn i see how much it might be, i see a good price from a non amazon shop, then a long weekend passes and it is now a Tuesday, so i bash in that isbn and no results from that hit appear. Not a problem as i soon find it, redo my isbn and proceed to purchase it being cheaper than the results from the usual suspects.
Shopping is not just price based, but other things become important, and there are sites like ebay who i dont trust. The point is if google* become to be a small bubble of suppliers who are not the best then the use of the search is a little redundant.
I proceed to purchase from the non listed supplier, and it is painless.
* i cant use Microsoft for patent and other fud reasons if you think im being silly, and the issue i raise couldhapen to any other search engine as well
