Where can I find purchase history of App Store?

I have purchased various apps over the past few years. I used to be able to see my purchased app in iTunes . It showed app purchased, the amount paid & date purchased. It was helpful when I needed to re-download an app & prove I purchased it in order to reinstall it.

My question is where can I find that information now as it was very useful?
