Changes: I think it would be nice to change something in the chestshops. For example, when your shop is out of stock you don't want people spamming your shop with that message over and over again. So I was wondering if you could remove that. (Yes I know you won't know when it's out of stock but you can at least check the chest or someone could inform you). Donating chests? This is just a tiny suggestion and I know we have hoppers for those. But thought I could suggest it. And if it ever worked the 3rd line would say "Donation". Thanks you for readin this suggestion.
1: take it up with the plugin developer of chestshop 2: just make sticks and sell then for the price needed, or cobble or something.
