Received private sales offering from Shuuemura-usa for 20% off. Wouldn't work. Commerce gave me another code for 20% off. Didn't work. Promo said the discount was "sitewide." Ecommerce after many different stories finally said it only applied to beauty products -- which meant it was not sitewide. They, after many calls, came up with the story that hair products was a different site. However, if you go to shuuemura-usa, you can then click on hair products. False advertising and extremely poor customer service. Not ordering from them.
