Mercenaries 2, Mirror's Edge and Dead Space can currently be obtained from http://eastore.ea.com/store/eaemea/en_G ... ayHomePage for the princely sum of £0.00 .
You'll need to add all of them to the cart before the discount appears, no payment details required.
Seems that they were originally priced at £14.99 each with a bundle discount, and when they dropped the price to £4.99 they forgot to drop the discount as well.
