I’ve been using Uprint and Mail for several posters printed in different sizes, on different material, and had them shipped to different conferences etc. The quality and price are much better than Fedex, and the service is always top notch. One year, for a large NSF conference that USAI and the VA hosted, Uprint printed tri-fold flyers, and ring-bound books at the last minute and prevented a disaster from occurring. I won’t use any other print and mail service!
