I called up the sign shop that I got my coroplast from to see how much a diecut bumpersticker sized window sticker would be. Didn't really get an answer BUT if you can email me your design I can email it to them and they will price it out for me. Also they are local for me so I can pick them up and actually TALK to a person. If you want me to give that a shot let me know. I was also debating getting a sticker made for the rear window in the style of the white oval with black border and lettering that said something like 60+MPG in 40 50 60 and maybe a 70.
