634 only includes what preorders we bought in September, there was around another 300 on top of that for other CE related purchases (maybe more).
Also, just remembered that that was also with me cancelling most of my early September items and losing out on quite a bit of my September spending money as I was at Gamescom in August
So cancelled a lot of stuff to take spending money
This month, my preorder money is similar, around 700ish.
Between now (17th October) and Christmas, I've got around ?1650 worth of preorders to pay for (again, not including other CE purchases that aren't preorders) xx
