Pokemon X & Y launch worldwide this week, and Tesco wants UK trainers to buy it from them. In co-operation with Nintendo they're offering a Serial Code with purchases of promotional copies of either version of the game, which can be redeemed for 12 Quick Balls.
As all good Pokemon trainers know, a Quick Ball gives you a higher chance of a successful capture if it's used early on in a battle. 12 won't help you catch 'em all, but it's a start!
Pokemon X & Y are released on Nintendo 3DS worldwide on October 12.
Thanks, Nintendo Life.
