The Apple Store offers three factory-refurbished Apple Mac Pro workstations in its Special Deals section. Plus, all systems receive free shipping. At up to $850 off, each system is the lowest total price we could find. Plus, all are lower than the best price we could find for a new unit, typically by wide margins. Sales tax is added where applicable. A 1-year warranty applies, the same as new systems. Items are removed from Apple's site when they sell out. The systems:
