That's a ridiculous statement. How do can you expect new players earn 50m-120m for someone like Julian or Marshal? I've seen players with hardly a bell to their name desperate for particular villagers and still they can show how much they want that particular villager in their town. Now I understand that some people may want bells for a villager ~ personally I don't agree with this but i can understand how it's happened with how many people want popular villagers on the boards.
Simply because someone has more bells they are willing to offer does not under any circumstance relate to how much they want said villager. One is material, the other is immaterial that cannot be measured.
If the OP originally promised a dream villager to someone, unless something goes wrong/that someone shows signs of suspicious behaviour, that someone should receive her/him or else it just comes down to someone going back on their word.
That's what I meant. There's some people who can't afford to buy a villager for 50m-100m, and I think it's awful that someone offers something, the person who owns the villager accepts the offer, and then puts it up on auction to get more money, instead of selling it to the person who has it listed as their number one dream villager.
