I am lucky enough to have a local shop (PJ's Camera) that still carries color paper, at least in 8x10 (and a bit of 11x14 I think). Otherwise, Calumet as there is a branch relatively close. On grand occasion (or when I can't wait) I will drive to Chicago where there is a much larger Calumet outlet, Central Camera, and Helix (alphabetically). The nice thing about the closer Calumet store is that if they don't have it in stock, they can get it from Chicago the next day without a shipping charge.
