I made an account to review this, really useful plugin not requiring another plugin and no central currency. I hope the developer keeps updating this because this is great. Works in 1.21.4.

This shop system is such a classic! It reminds me of when I first started playing Minecraft (back in version 1.1.1) – this kind of shop setup was already way ahead of its time! Haha, I absolutely love it so much. It's super easy to set up, and so far, it's working perfectly on version 1.21.4. I'll keep testing it further, but everything looks great so far. Please keep updating this amazing plugin – love you, dev! ❤️
