The beloved cheap authentic: a £15 supermarket sweep of British biscuits and tea beats any gift-shop bag, and it's genuinely unavailable-or-triple-priced abroad.
Price: 2.25 GBP (Sainsbury's standard shelf price (supermarkets range £2.25-2.80))
Where to buy: Any Tesco/Sainsbury's — do a proper supermarket haul: Digestives, Hobnobs, Jaffa Cakes, Yorkshire Tea, Cadbury (UK recipe), Marmite.
