Waterlooplein, Albert Cuyp market, Noorder market and many more.
These are the places for students to find all their bargains.
Waterlooplein has second hand bikes, which are a must in Amsterdam as no bike will last for a very long time so spending a lot on one is useless.
Albert Cuyp market has a large variety of fresh foods and also has markets selling everything from the Etos and Kruidvat, but cheaper.
Then there's the Noorder market, a real treasure trove of leather boots, jackets, antiques, etc.
Big bike chains are also sold everywhere, which are definitely good to have if you want your bicycle to last a little longer in this city!
The thing to remember is: where can I get it cheapest? Of course, when shopping for clothes or a laptop it is best to do so in a good shop. However, saving a little of shampoo's, food, bicycles, boots (and many other items) is a good step towards having more money for rent and social activities, of which there are many in this city!
