First of all, you will have to reference the shop spawn coords
command /setshop:
permission: op
trigger:
set {shop} to location of block at location of player
send "Shop spawn set to %{spawn}%!" to player
Then for the /spawn command
command /shop:
trigger:
teleport player to {shop}
send "Teleported!" to player
