From the website: "UT Slapsigns are available on the street at all home games for $50.00 (including tax) or online for $65.00 (including tax, shipping and handling).
Our sign is 27″ x 8″ and made from 1/2″ MDF board. Each is cut using a computer-guided router to the highest possible detail given the size requirements. They are sanded, given two coats of UT orange paint, vinyl wording is applied, and a coat of polyurethane to protect the finish for unlimited slaps. They are made to fit above standard interior doors."
I actually bought one from this guy this past weekend and he only charged me $40 in cash no tax.
