I accidentally saw one that he had put a 'Best Offer' on, on eBay, so not just browsed at, bid on, and I don't like the colour 
I know this is totally a first world problem, but we are having a new kitchen put in next year and whilst watching the GBBO I was remarking on the fact that I planned to buy one once the new kitchen is completed and was excited about it.
He has (very sweetly and generously) decided to buy one for me as part of my 40th birthday present. He was with me by the computer as I scrolled down past it as I had just bought a small item for my son using his account, so he knows I saw it but must be hoping I didn't twig.
Question is; do I tell him I saw and give me the opportunity to guide him to a colour I really want. Or do I keep the pretence up that I didn't see anything and be jolly grateful with whatever he chooses because he had such good intentions and is lovely.
Btw don't think in going to have the opportunity to swap it or anything a he doesn't seem to make purchases from shops like John Lewis for some reason.
