I'll start by saying, don't buy the DLC. Trade your game in and just get the TTK version of the game, as described below. 1. Open a TopCashBack (TCB) account here - https://www.topcashback.co.uk/home 2. Using TCB's search box, search for rakuten.co.uk, current cashback is 5.25% 3. Click the link to get to Rakuten, and place game in basket. You can currently get it for £40.95 on the site. 4. Use the code SEP10 to get 10% off the game. Order the game. 5. You get 200 reward points, worth £2 to use on a future Rakuten visit. Total: £40.95 - £2.15 (TCB) - £4.09 = £34.71. Don't forget the £2 of reward points. Hope this was helpful!
