Is there any site on the internet that offers spiff information from
all different IT product manufacturers and easy claim processing ? I
am talking about one central site that gives information on all
rebates/spiffs/promotions offered to resellers/consumers by IT
manufacturers (such as IBM, Compaq, 3com, viewsonic....) and also
ability to claim those rebates/spiffs ?

Hi abaig...

From what I can tell, PC World offers the most comprehensive
listing of manufacturer's rebates, at:
http://pcworld.pricegrabber.com/home_rebates.php/


Searches, via Google:

rebates + manufacturer
://www.google.com/search?num=100&hl=en&lr=&ie=UTF-8&oe=UTF8&q=rebates+%2B+manufacturer&btnG=Google+Search

There are 153,000 results from that page, but from what I saw,
you will not likely find a more thorough listing of manufacturer's
rebates than on PC World's site.

It would have been nice to get a listing of at least 3/4
sites..specially any providing a claim processing service..unless such
sites donnot exist.
Eitherway the answer was helpful, I did not know of pricegrabber
rebates.

agaig-ga,

I did search a considerable number of the results from the Google
search, looking for a claim processing service such as you suggest.
I came to the conclusion that they do not exist, outside of reseller
sites such as PC World. In the future, I will be certain to clarify
these things in my responses. Thank you for the useful feedback.
