Absolutely disgusting stuff, but dirt cheap.
I once attended a 10 week summer school at a university, where we had accommodation and meals for free, as well as 60 quid a week bursary. Not having anything to actually spend money on, we bought obscene amounts of Fink Brau from Lidl and 4X from the other supermarket nearby. It got out of hand when we were turning up at breakfast with a beer, just because we could. The summer school itself only had 12 hours of lectures a week, so we were left with the rest of the time to do absolutely nothing but drink.
I still remember my friend (now a respectable Army sergeant) getting smashed at breakfast before one lecture, and we were routinely taking a couple of beers to the canteen in the evening. We were only obliged to attend lectures, but we were under no obligation to actually study or do anything apart from that.
