How cheap are the drinks in your union bar?

All the booze you guzzle each year amounts to 500 pints. 

And if each one costs an average of £3, you could end up spending £1500 on alcohol, depending on how hardcore you are.

Student union bars pride themselves on serving bargain beer — but who pulls the cheapest pints?

We ranked each SU bar on how cut-price their pints, jägerbombs and double vodka mixers are.
