Here's the scenario... you buy a CD for £10, you lend it to your friend who breaks it by accident and they give you replacement money for the CD. BUT, the CD's price has been reduced (since it's after a few months since you bought it) to £5. The CD is factory sealed, like the one you bought originally, so do you think you should have £10 or £5?

I'd say £10 because I did ORIGINALLY pay for that, and if I ever wanted to sell it I wouldn't want to make too much of a loss.
