Shop beside Buckingham Palace which deals with items certified by UK Gov, Any1 know of such shop? Shop Name?

Question

I am trying to look for this shop so that I can get Tea in cans for my Japanese friend. I need the shop name and if possible address or website. The tea she is looking for has a code "BP EMB TE" at the bottom of the barcode.

Answer 1

Fortnum and Mason is THE shop in London for buying tea.
http://www.fortnumandmason.com/

Otherwise the gift shop at Buckingham Palace sells tea.
