Maybe it's valid, but there are duplicate Primarks here.  See https://map.atownsend.org.uk/maps/map/map.html#zoom=23&lat=52.6366538&lon=-1.1306313 for a zoomed in example.  Also there are 3 H&Ms to the southwest.  I suspect that this is due to adding the "shop" tag to "rooms" that make up part of a larger shop.
