I must disagree so heavily with you here. Prices can depend on so many factors, but.... when that particular account is choosing that particular machine, AWS knows what it will cost, and they can show it to them dynamically. It's very difficult to be convinced in this day and age that you cannot have a dynamic price chart right beside the machine sellector which is showing or calculating prices in real time for that particular product.

About using IaaC to set-up the infrastructure, sure, but sometimes you just need to browse stuff before actually writing code to get a feel.
