Superdrug

Superdrug at Silverburn is a spacious and well laid out store, which has all the standard Superdrug goodies and is also open quite long hours, great for a beauty treat top up.
I was in to get nail varnish, and they have everything from their own budget range up to well known brands and also accessories and make up bags. It is easy to find what you are looking for, and there is a big choice in some of the ranges (particularly shampoos). Even in winter this branch had a small section of travel staples, so if you are looking for flight size travel things this would be a good place to head to.
It seems to be a busy branch, but when I was there they opened extra tills when the shop got busier, so minimal waiting time, and friendly service too.
