I was at Walgreens today, and they didn't have any mini-eggs, either.
They did, however, have Barocks:
I suggest blowing up that picture and inspecting the selling points.
I live in Hyde Park, a neighborhood on the South Side of Chicago, about 4 blocks from the recently vacated home of our president and his family. As such, this is my Walgreens. Even so, it's a little strange to see a politician so widely merchandised - growing up the closest I ever came to this was the (joking) Free Buddy campaign in Providence, anybody remember these?
So I didn't buy a Barock. ($9.99 seems a little steep, even if it is a real rock.)
EDIT: The Barock has been outdone.
