Dell Home, via its Member Purchase Program, cuts up to $114 off a selection of its Dell desktops and laptops. Better yet, take an extra $50 off select PCs priced $499 or more via coupon code "SAVE50" or an extra $100 off select PCs priced $999 or more via coupon code "SAVE100". Alternatively, Dell Advantage Rewards members can apply coupon code "REWARD10" to cut an extra 10% off all systems, which may yield a better discount on select PCs. (Not a member? It's free to join.) Plus, all items qualify for free shipping. Deal ends October 20. A couple of best bets, with prices after "REWARD10": Note: Dell's MPP is available to select groups, including students, government employees, military (active and retired), credit union members, and health care workers.
