Shop

I was looking for some cool ideas to make, and then thought that remaking a Shop in Skript would be pretty lit, because I can't find a fully-featured, well-working one out there. And so here we are.

Before you read the features and commands, please read this! I am well aware that bugs and glitches may occur! Please report these to me and I will release a fix ASAP.
As well as bugs, you may also want to add or remove a feature. To:

• add a feature - explain what the feature is and how the player would use it
• remove a feature - give a super good reason as to why it should be removed, as removing a feature is a BIG deal

Another thing that you should know is that I haven't tested this fully! The Skript was not rushed, but due to school (and other reasons), I haven't had too much time to test!
So, basically what I'm saying is that if you find ANY bugs or glitches, PLEASE notify me and I will fix them as soon as possible! Again, sorry in advance for any issues!
