My better half thinks that I've spent too much money on books this year (shared credit card statement :P). How can €2000 ever be too much? I only go for the good deals and (almost) never pay full price :P
If he only knew how many books I actually leave behind in the stores - both the on-line and physical ones!
If you ask me you can never have too many books nor can you ever spend too much on them (at least not when you make good deals)! They are my preciousssss...!
