No, it cannot due to the mere fact that offers and value are so subjective that the buyer can never tell what the seller considers a "reasonable" offer. The same exact item for two different people may hold a far different value.
Yes, but come on. Reasonable in this context doesn't mean only what the buyer wants to pay; it obviously means something not too far from what the buyer is asking. Surely any sensible person would read it that way.
Suppose you're selling Entwistle's Buzzard bass, and you're asking $20,000 and saying you'll consider any reasonable offer. I offer you $50. No sane person would call that a reasonable offer--even though the Buzzard bass may be worth no more than $50 to me, since I would never use it and don't really want it around. To make that kind of offer would just be insulting and dumb, and I can't see how you could consider it reasonable.
