Scoreboard Shop

Firstly, you need to create a scoreboard objective using Minecraft's /scoreboard command. For example, we want to record how many zombie killed by the players:

/scoreboard objectives add zombieKills minecraft.killed:minecraft.zombie

We can set the display to the sidebar by:

/scoreboard objectives setdisplay sidebar zombieKills

Then, we link the variable with SBS and call it KillerGold:

/sbs link zombieKills KillerGold

We also need a category to display the goods:

/sbs category create cateA KillerGoldShop zombie_head

After that, we can add goods to the category. The good can be either item from your hand or any command.
e.g
From you hand and sell at 100 zombieKills score:

/sbs item create cateA zombieKills 100 Display_name Lore HAND 1

Sell the command which change weather to clear at 500 zombieKills score:

/sbs item create cateA zombieKills 500 Display_name Lore COMMAND sunflower /weather clear
