I have never seen a code for Plazatoo. Regarding their customer service...it's not great! I ordered a Kooba Braeden from them and it came with the ink security tag on it(don't know what you call that thing). What was so stupid on my part was that I put the bag away in my closet in the box in which it came without even looking at it! How dumb is that??? Six months later I take it from the closet thinking that I would carry it and discovered the ink tag. I had to return it to them in order to have it removed and they didn't offer to pay the shipping!I bought some shoes from them in the Fall and their service was pretty bad. I would definitely stay away unless it's something you really want and are prepared for a potential hassle. Again, no problem with authenticity.
