SOGA - business to business, rejecting faulty goods
We have some mice here which have developed a fault. They are virtually brand new.
Our supplier is telling us that because we have had the item(s) for more than 5 days, we must now contact the manufacturer for replacements.
I'm very brushed up on the Sale of Goods Act insofar as consumers are concerned, but not so where it is a business to business sale (or business to school in this case).
Is the supplier right in this instance, or are they trying to pull a fast one?
