Side note: Stng is now selling harm 2 potions in his shop. I think this may be causing problems with newer players who might be tempted to buy and throw. Its a gateway for everybody without a brewing stand. Please do not misinterpret me. I am not telling players what they can and cannot sell, it's simply that its so close to spawn, and so easy to use. Business wise, the strategy is great, as its a rarely acquired item with high appeal to players. If the shop was in a less accessible area, it might not work out, but this brings interest to new players looking to start their pokemonserver adventure with a bang. Interpret this how you want to.
Edit: Dang. My ADHD just kicked in. How did I get to business strategy...
