The plugin looks cool, I believe it still has a future, it just needs updates.

Excellent plugin and very easy to use, could you add more translation messages? Especially when the purchase is confirmed, thanks

Lightweight, easy to configure, have in-built shop, permissions. Good plugin overall!
I have a suggestion for option to ignore exp bottles. Since there are plugins allowing you to store exp in them and then you can throw those bottles to effectively dupe exp.
