The couple who have everything

What do you buy each other when you have everything? Books are always good. Really looking to diving into this lot.
That said, I cracked the screen on my phone while we were away, my little camera has a faulty zoom and today I realise that the hinge on my laptop is squiffy. So I guess any of those would have made an excellent anniversary gift. Between these and the new washer it's turning into an expensive month. Hey ho, you can't take it with you.
