I have to give a shout out to Garston Sign Supplies. They are my local supplier, they span from new york-penn to mass area. I used to do a ton with them back in the cut vinyl days, lately they have become just my substrate source.
Two shout outs! One, they finally implemented an online ordering system that rocks. Two, I usually order my digital print media from Fellers because they always seem to be the lowest price around, but I saved $100 on two Arlon wrap kits today!
