If you decide to go print at Kinko's or another printer, make sure to save your digital receipt. I think most times you are allowed to print off what you've bought, so that should be something that you can provide I believe.
Printing them out at a printer and having them bound is my selection of choice.
The only other way that I do, is if I print it off myself, and then use a plastic folder (seems to better protect them overall from the elements if I'll be taking it outside on it's own) to house it in.
