Idea: Online stores could provide shipped orders in a form of checklist

Checklisted order summary can help check delivered items, especially on large orders.

I've got my delivery recently and to check if I've got everything I have to either export order list to some app and check items I pick from package (first-picked-first-checked-out), or take all them out and go through the list line by line and check if I have this item (and put item aside)
