I can always find more.

My bank balance may have breathed a sigh of relief when I got caught up with X Factor trade paperbacks, but I bought the first Scott Pilgrim book this morning.

Now it is cowering in fear, and I am trying to resist the call of amazon.co.uk.

Edited to add: the resisting lasted as long as it took me to see how much amazon had knocked off the price, but I did manage to restrain myself to just the next 2.
