Problem description:
When you use the verb "Buy a wand" the game is supposed to check you for /obj/wand. If you don't have a wand, he checks your money , if you have enough , he talks and gives you a wand. once you have the wand, and you talk to him again, he still talks and gives you a wand.

You'll need to utilize the locate() proc, as it stands you're simply checking for a type-path inside of a list, which it won't find.

var/obj/my_obj/O = locate() in contents
if(O) // If the player has a my_obj
    // do stuff
else // If they don't
    // do other stuff.
