The Apple Store has restocked a selection of factory-refurbished Apple Mac mini computer models. With free shipping, that's up to a $250 off and tied with our mention from last week as the lowest total price we've seen for any of these configurations, which were originally released in July 2011. Sales tax is added where applicable. A 1-year warranty applies, the same as new systems. Items are removed from Apple's web site once sold out. The deals, each with free shipping:
