There seem to be 4 Boots in the centre of Birmingham listed on the Boots site but 6 Boots tagged on the map. I'm not sure which are which.

This one seems to be correctly identified as the one on High Street
https://www.openstreetmap.org/way/110491701
And this one is Brindley Place:

Which leaaves 2 actual Boots stores. These are the 4 mapped stores:

One of these is Unit 11 Concourse Level, Birmingham New
and one of them is 
Unit Msu 10a, New Bull Ring Shop Centre.
I assume that the other 2 are closed.
