Something for Xmas?

Today, while searching for something completely different, I came upon a rather intriguing object on Amazon and it certainly got me wondering.

It's a Five Year Diary.

Okay, I can hear you saying, what's the problem? But friends, this is no ordinary Five Year Diary, no... this is a used Five Year Diary and its condition is, according to the sellers, 'Acceptable'. And the price I'm hearing you ask?  £1.50 + £1.26 UK delivery.

What's even stranger is that there's another used Five Year Diary for sale and this one is a hefty £24.00 + £1.26 UK delivery. I'm not 100% sure that having it in 'Very Good' condition makes it that much better than its rival, but I'm sure there must be reasons.

Given that you can buy a new Five Year Diary for £3.33 and it does come complete with a pencil and padlock (alright well it does have the slight downside of being a One Direction Secret Diary - and I'm sure anyone in their right mind who bought one of these would want it to remain a secret) I think I must be missing the point here. 

Please someone, tell me who buys this stuff?

And just in case you don't believe me, here's the link .
