I used MS Powerpoint to do A3-sized slides to print in colour. The upload was simple, the docs were well-packaged, and arrived three days later looking good, printed right to the edge of the sheet as the web site indicated they would be. My only complaint is that, for my first print job the options on printing to the edge were not explained clearly, and that for my second print job my path through the web site didn't even seem to give me an option of not printing to the edge. I had used the ruler in Powerpoint to design a text box of a particular size, so it was frustrating not knowing how to print it in exactly that size
