I always have a number of books in my 'Save for Later' section of the Basket on Amazon which are books I desperately want but feel too guilty to spend money on. If I had to choose two I would probably go for:
This is a hardcover copy of Jonathan Safran Foer's 'Everything is Illuminated' and 'Extremely Loud and Incredibly Close'. They are two of my favourite books of all time and this copy so pretty! I love it so much. I want it so badly, but as I already have copies of both books it is hard to justify buying it.
Those two books plus HUNDREDS more.
