Just got off the phone with these people - John the owner. For being an owner, you would think that the person would be more helpful in explaining what the process is in getting a poster made.
I'm helping a non profit organization and was trying to figure out what the costs were for different sizes. After giving me one size he basically just assumed that I didn't know what I wanted because he never bothered to ask the right questions, nor did I really have the chance to explain.
When someone tells you, "why don't you figure out what you want and then call back." It tells me that I need to go elsewhere for better customer service. Sorry John, that's why I was calling, to find out different costs which dictate what I want or can afford with the budget given. Had you listened long enough, you would have learned that eventually I would probably buy 500 of various sizes.
