I do see prices when I look at the instance selection box. "On-demand linux base pricing: 0.0104 USD per hour" for t3.micro (matching the published pricing). it does not show the full price (based on any additional volumes or other configuration details).

It gets far more complicated when you have reserved instances, and combine reserved instances with RAM sharing when working in a larger org.

Not back when i was using AWS

You can upload an image to imgur and show us. I don't see this.
