Cart component using flexbox

This is the first challenge I have completed after having failed to complete 2 intermediate-level page layout challenges. Fortunately, I found this to be easy i did learn how to centre stuff on the page and used letter-spacing for the first time. Any and all constructive criticism is welcome especially if it's related to improving code quality to a professional standard.

I choose to use flex-box because I thought flex-grid was overkill but would like to know if there is any other way of achieving this look with less code?

Can someone recommend another challenge or set of challenges that would help me progressively level up to the intermediate page layouts (EasyBank Page Layout) and hopefully find it easy in the next attempt?
