I bought a copy of the UK version of this and the substance that you scratch off wouldn't come off
correctly and as a result you couldn't read one of the numbers. Penguin was nice enough to send a
replacedment and I hd the same issue and I was INCREDIBLY careful scratching it off the second time.
Maybe it's an issue with the UK version? Anyway, I had to throw that version away too. At that point
it just became a $25 loss as I didn't want to ask for a 3rd copy.
