Trade Sign Plugin

There should be a trade sign plugin! It makes selling items so much easier and you don't have to do it manually. What u guys think?

I thought we already have that at the shop?

Idk but if there is could you tell me how to do this?

I remember when I started on runecraft thats when players could do the sign shop. I think that was a good way to bring in money.

Well there are sign shops at /warp shop but for chest shops heres an example.

Fountainmog
15
B 100:50 S
Wheat

that's great fount but what does everything mean? what is the 15? what is 100:50?

15 is the amount
100 is the buy price
50 is the sell price

15=quantity of product you are buying or selling
