This was seen on Mumsnet recently. in I Can't Stand Them!

‘’To be disappointed about the book?

My daughter is in her mid-twenties. For Xmas she bought me a slim paperback book. I thought at the time it was a fairly modest gift but thanked her and put it on one side.

This evening I picked it up to read. I found she had omitted to rub out the pencil price put in at the charity shop. The book had cost £2.49.

I would like to have been worth a tenner.’‘

Oh, woe is you! Wah wah cry cry! If it’s not expensive enough then give it back to her and GROW UP you stupid selfish childish old bag!
