The Apple Store offers four factory-refurbished Apple Mac Pro workstations in its Special Deals section. Plus, all systems receive free shipping. At up to $530 off, each system is tied with last week's mention as the lowest total price we've seen direct from Apple this year. 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:

• Apple MC560LL/A Mac Pro Quad-Core Xeon 2.8GHz Workstation for $2,119
• Apple MC561LL/A Mac Pro 8-Core Xeon 2.4GHz Workstation for $2,969
• Apple G0LG0LL/A Mac Pro 12-Core Xeon 2.66GHz Workstation for $4,249
• Apple G0LG1LL/A Mac Pro 12-Core Xeon 2.93GHz Workstation for $5,249
