Seen any high resolution generic -grocery product images?

I am working on a prototype product that advertises a lot of grocery store products(from diapers, to doederants to snack foods...etc..)I was wondering if anyone has seen high resolution images of "generic" logos, products - i.e.- instead of Coca Cola it is "Cola". I am being a bit lazy and am trying not to have to create all these products from scratch.
Thanks for your time.
