Jen, if you ever go south to the Provo/Orem area, there is a store called "The Paper Store and More" that sells kraft A2 envelopes. They are about $5.50 for 25 envelopes. They have a pointed closure rather than the straight closure of most kraft envelopes. Here is a link to their site: A2 ENVELOPES
They also have reams of 8 1/2 x 11 card stock in a variety of colors. It's not nearly as good as xpedx, but if you are down that way anyway, it is convenient.
