The Apple Store discounts a selection of factory-refurbished Apple Mac mini desktops and servers, as listed below, with prices starting at $509. With free shipping, that ties our mention from a month ago as the best discount we've seen since Black Friday. (A 1-year warranty applies to each, the same as new systems.) The deals, with prices compared to the best deal we could find for new units elsewhere:
