SoftwareMedia offers Total Training for Acrobat X Pro: Essentials for PC and Mac, model no. TACBTX, for $59 with free shipping. (Select "Free Budget" shipping in-cart.) That's the lowest total price we could find by $10, outside the price below. (Most stores charge over $80.) This training software teaches you to create, edit, and distribute PDF documents "like a pro."

A close price: HP Home & Home Office Store has it for $59.99 with free shipping, but also charges sales tax in more locations.
