Dell Refurbished Store takes an extra 55% off any factory-refurbished Dell OptiPlex 9010 Desktop PC via coupon code "55DESK9010". Shipping starts at $21.99. For more expensive configurations, that beats our mention of 50% off from Black Friday week (which included free shipping) and is the best percent-off discount we've seen for these systems. Dell refurbished systems are covered by a 100-day Dell warranty. Deal ends January 16.
