My go-to beer when I was broke was this
Dude Beer.
It was the cheapest beer I could buy at a B.C. Liquor Store at I think $7.99 a six pack, and it was warm. Sadly though, in B.C. there's only two places to get booze from, a Government sanctioned liquor store where prices are lower but nothing is refrigerated, and a cold beer and wine store, usually associated with a bar. You could also do off-sales with a bar for a six pack, but that was usually the most expensive. I remember a 6-pack of local beer costed me $16 from an off-sale.
So that beer was my go-to beer for being cheap as well as deterring my roommates at the time from drinking all my beer. They'd go as low as to drink my Molson Canadian, which is pretty much like drinking moose piss, but they wouldn't drink my Dude Beer.
On topic though, I'm drinking a warm milky cup o tea.
