I can't find quickstock. I've been on subeta for about half a year now, but I didn't even know there was one until I noticed some people mention it. Can someone tell me where it is? That would be really helpful.

Go to Your Shop - Choose a Shop - Quick Stock

The trick is that you have to get there through one of your shops :)

@ Yarwel Your Shops --> Pick a Shop --> Quickstock is at the top, beside Edit Items

thanks guy's that's really helpful
