Code:
mob/proc/bsradar_sales()

    var/cost = 1000000

    switch(input("Want to buy this Radar(1 Mill zenni)?")in list("Black Star Dragon Radar","Never Mind"))

        if("Never Mind")
            return

        if("Black Star Dragon Radar")
            if(usr.zenni >= cost)
                if(usr.inven_min < usr.inven_max)
                    usr.zenni -= cost
                    usr.inven_min ++
                    usr.contents += new/obj/Equipment/Consumable/Black_Star_Radar
                    usr << "<font color = white>Shop Keep:</font> Thanks for buying!"
                    return
                else
                    usr << "No more room for items."
            else
                usr << "<font color = white>Shop Keep:</font> You cannot afford this!"
                return
