Now to me - and I'm curious as to how you all feel on this - this behavior is extremely rude. Of course no seller is ever obligated to accept any offer, however, I consider declining without a message or counter offer to be reserved exclusively for insultingly lowball offers. I think posting a Make An Offer option obliges the seller to certain level of conduct when dealing with reasonable offers, since they are openly soliciting for offers. I have no problem whatsoever with someone selling an item with a Buy It Now, and I will either pay their price or I won't. But take that same seller selling the exact same item with the exact same Buy It Now price but with Make An Offer set on the auction, who then declines all offers and just wants the Buy It Now price anyway, this upsets me to the point where I will permanently blacklist the seller. If you don't want to accept offers, don't solicit them. It would have been one thing if they declined and explained that Make An Offer had accidentally been set on the item and that offers are not being considered, but they couldn't even be bothered to do that. Now it is possible that they would have sold the item for 19.50 or so, but to set Make An Offer on an auction to attract business when you're only willing to go down half a Euro is petty and infuriating as well.
