Try this:

command /shop:
    trigger:
        open virtual chest inventory with size 2 named "Special Shop" to player
        format gui slot 0 of player with emerald named "&a&lDeath to all mobs" with lore "&aUNCOMMON" to run:
            open virtual chest inventory with size 2 named "Special Shop" to player
            format gui slot 0 of player with emerald named "&6&lEmerald Key" with lore "&6LEGENDARY" to run:\
                if player's inventory contains 500 diamonds:
                    remove 500 diamond from player's inventory
                    give player emerald named "&6&lEmerald Key" with lore "&6LEGENDARY"
                else:
                    send "(Message Here)"
            format gui slot 1 of player with name tag named "&6Free Warden helmet" with lore "&6LEGENDARY" to run:
                kill player
                broadcast "&cDon't be greedy %player%, they were trying to scam the the shop out of warden helmets!!!"
