I actually bought the script, and like it alot. The only thing I would change is..
Making it so that say, I get down to 6k gp it doesn't stop the script, maybe give it an option to wait with the script paused, so my mule or me can trade him again, and just click play. Instead of having to go back in, load your settings and boom, just makes it more smooth but still loved the script, been searching for this foreverrrr!
