Device purchase history

Helpful, but not quite what I was looking for. I have bought multiple iPhones and Apple Watches plus several cases, MagSafe chargers, etc. over the past couple of months. I'm trying to determine the amount I spent for each of these items. I don't seem to be able to do that unless I do it at the time of ordering. After that it, unless I remember the order number, I can't figure it out. Apple doesn't seem to keep order history the way for example, Amazon does.
