Dell Home coupon: Buy one desktop or laptop, get 2nd for 50% off + free shipping

At Dell Home, buy one Inspiron 1525 or XPS M1530 Laptop or Inspiron 530s or Studio Hybrid Desktop and get a second one for 50% off via this link. That's the best percent-off coupon we've seen on these systems. Plus, receive free shipping. Sales tax is added where applicable. Deal ends August 13.

Of note, you can mix and match; both don't have to be the same exact system.
