I'm actually a seller on Zazzle. I'm sorry to say Zazzle really doesn't consider the sellers their customers. I find we are the lowest priority. The reason most products come out as well as they do is because we design them well. Unfortunately we are often not paid reliably.We have items removed for copyright infringement even if there is no infringement. We have to hunt down and research problems that are usually mistakes made by Zazzle or their software. We are generally talked down to, ignored and made to feel unimportant because we aren't the "real customers" We promote our products, properly tag and name them, display them to sell... we make Zazzle profitable but to Zazzle we are just sellers.
Zazzle has major communication and customer relation deficiencies. They don't know how to run the business end though they have a decent machine for designing products. For now that is what's saving them.
