Well, that there is no possiblity to do price comparisions fully
automatic is a drawback from the point of view of the customers.
I don't thik most of the vendors see this as a disadvantage.

Even if all catalogues are XMLified, which is quite difficult in
itself because of the differeent significance of attributes for
different product categories, vendors can work around easy
price comparisions by using complicated conditions, like "you
get a 10% rebate if you buy this and that on sunday evenings
and deliver to a Texas PO box".
