Everything about working with Vistaprint has been great, however, the puzzle pieces in a 500 piece are almost identical in shape. It makes the puzzle more difficult and a little redundant, but I guess some people would think it makes it more challenging. I'm not sure which I think yet, but when looking for pieces, they all seem like they might fit in the same-shape matches... if they have similar colors, which makes it difficult in a way maybe it shouldn't be. Seems easy to fix if a computer is randomizing the shapes of the pieces when they're cut out. Otherwise, everything else is cool.
