Very grey area based on the info you have supplied... If a price was "never agreed", clearly no verbal contract was entered into. If a supplier is claiming a verbal contract was entered into, it is for the supplier concerned to prove the likelyhood (not necessarily 'beyond all reasonable doubt') that this was the case. If he/she is able to prove a price WAS agreed verbally, it still leaves the situation open to legal deliberation. Id est, a price may have been agreed, but was a quantity agreed at the said price? As I say, it's not black and white.
