I had an issue with a package not arriving because of the delivery company just not delivering. That wasn't society6's fault so I contacted the customer service to try again and get a replacement order shipped out.
The customer service was really good, replied within the same day and shipped out the replacement as well with no additional fees and also gave me all infos I needed to know about the replacement in an additional email.
All in all a very satisfactory service and I will order again!
