uhm..
only 14 people can buy that pokeball for 18.000 bells.
2 of them are NPC profiles ( profiles of the site itself, and not people )
2 others are Mods ( or something ) 1 has a red name and 1 has a green name )
( and i think every one of them have all collectibles )
and that leaves 10 people who can buy it.
don't you think 18.000 TBT is a bit much ?
i do get why you'd sell it high since it's a rare item.
but still though
