I've got 1.1k AC and no real use for it since I've bought the stuff I wanted already.

I have both shops open! I can buy stuff from the main shop, and the Veil Nebula shop.

Trading at 20AC = 1GB

Will take GB pure, but also will take items in exchange as well.

Energy boost - 2gb
Honeycomb - 2gb
Egg yolk - 3gb
Giant tortoise - 2gb
Buffy balls - 20gb

I will look at other items for offer as well! These are just the ones I need and are at the front of my mind.
