I would be really leery about ordering
juice that cheap. I often find that there's a reason for juice being so cheap, and the last time I ordered stupidly cheap juice, it made me physically ill. Not immediately, but it crept up on me in very worrying ways.
As is often the case, you get what you pay for, though there are places even in Canada you can get cheap juice that's actually quite good. Jugheads, for example.
