I couldn’t believe they were charging $5.95 for each swatchbook. At all the companies I’ve worked at, these swatchbooks were given to us for free. So I would say call up Neenah, say you are with XYZ company, and they should mail them to you for free. I’m assuming the $5.95 is just for consumer customers, not for business customers.
