This APC 7-Outlet Uninterruptible Power Supply drops from $59.99 to $44.99 with free shipping at Staples.com when you pad your order with a low-cost item to get the subtotal to over $60 and apply code 30231 in the cart. For example, you could add this Tru Red Ballpoint Pen for $1.99 to get the code to work. Note that you won't see the price drop until after you begin checkout. This is the best price we found by $10. All outlets are surge protected. This offers up to 12 minutes of run time in the event of a power interruption. Sales tax is charged in most states.
