Firstly, if you check HDUK you can get 15% off your ferry trip like I did. This post is not just a tip for Game BUT also ToysRus and Carrefour who all have Wii's in stock.
Yesterday went over to Calais for £28 including the car. We found our way down the A16 towards Bolougne to Cite Europe, an absolutely massive shopping complex with lots of shops including a few english ones including tescos (no suprises there) and a big Carrefours.
We walked straight into GAME and got a Wii plus game for 249 euros,(do the maths here) a nunchuck and controller for 60 euros. Combine this with your christmas shopping and get booze & fags (not fags in Cite Europe though they don't sell them) to sell on to friends etc you could pay for your trip. We had a smashing day out and no longer need the sit by the computer or run around different towns looking for Wiis. Why pay Ebay prices etc Wii wii? xxx
