Dell Small Business takes an extra $50 off select laptops and desktop PCs priced $499 or more via coupon code "SAVE50" or an extra $100 off items priced $999 or more via coupon code "SAVE100". Plus, each of these PCs comes bundled with one to three years of ProSupport for free. (Duration is noted on the sale page.) Even better, these items receive free shipping. Deal ends January 10. A couple of best bets, with prices after "SAVE50":

Dell OptiPlex 3050 Intel Kaby Lake Core i5 2.7GHz Micro Desktop PC + 3 Years of ProSupport for $739 ($448 off)
June brings some big deals and sales, but you're better off postponing certain purchases.
