Ordered 3 sets of ten d4... one of the sets was wrong. We received the order on a Friday and tried to call right away... it was around 4pm in AZ. No answer and sent straight to voicemail. Same throughout the weekend. Called again Monday and had to call me back, he got back to me pretty quickly and said he would get the correct item in the mail right away. Hours would be a great addition on the site, but the dice are pretty and the situation was dealt with very professionally in the end.
