Students in the UK are often offered cheaper prices for many products and services when you produce your student or NUS Extra card (some require you to show both). If you are purchasing something in the UK, it is always worth checking if the shop offers student discount, as you could receive 10%-20% off, depending on the shop.
This can apply to clothes, restaurants, computers, cinema, stationery, museums…the list goes on! For more information, visit http://www.nus.org.uk/en/nus-extra/
