What the... Game reward points

[grayg1]

My last balance with them was about £3 odd in reward points (logged in last week ish). I haven't bought anything from them for like 4 months.
I just logged in and I have £11.38 worth of reward points.

I just logged onto my only bank account and no transactions there shouldn't be and my order history isn't showing anything new. The people in my family don't even know what a game reward card is so it's impossible to think they have used my card.

Where do I stand with this? I wanted to to preorder Wrath of the Lich King so I should just go ahead and do it (with my big discount)?

Edit: think perhaps someone has entered their reward card number in wrong on the Game website and so now I have their points? In which case they state in their terms points cannot be transfered to other cards etc.

Don't worry about it, even if it's an error it isn't worth their time and hassle doing anything about it. Just spend them and be happy.
