Drop boxes for mail have been around since the 1600s.
Congratulations, you don't live in an apartment building or condo where you might not have that option, or an area with a home owners association which may make it a hard proposal.
Not everyone can easily install a dropbox. Not everyone has a mom at home to sign for packages so they are there when you get home from junior high like you must.
My mail is kept in a lock box and shipments that won't fit are kept at the post office
And how late is the post office open where you are? It's not very frickin late here. 5 PM weekdays, which makes it pretty much totally useless. Having an option at a store that is open late is attractive to some people.
How many posts is it going to take for you to realize not everyone lives where you do, and is in the same situation as you? I'm tired of continuing to point out your ignorance.
