You will probably need to stock up and restock up on various kinds of stationery supplies (files, paper, pens, diaries, printer ink cartridges etc) over the duration of your course. From plain and simple, patterned and colourful, to university/college logo stationery, you will be spoilt for choice.
You will find shops selling stationery bits and pieces all over the place, but some shops are specialists and even if their stock may sometimes be a bit more expensive, it is usually of a much better quality and will therefore, last longer. You don't want to buy a file which will fall apart after 2 weeks. That would add up to quite a lot of files over a 3 or 4 year course!
