Not sure what you mean by pillaging customers exactly 
but I’m not complaining!
I’ll check my shop stands soon, it’ll be nice to have money to stock my request baskets at last. I hope you know that I’ll be spending a bunch of it right back at your shop - I’ve just discovered the joys of gem slingbows and will be buying more as soon as I can!
If you want to keep your stone stocked, I could be a supplier for you? Set up regular ‘shipments’ or something. Trading directly would reduce loss from tax, and I could offer a lower price than in my shop stands.
If you already have enough stone, then I can just keep stocking my own shop and it’ll be there when you need it
