What's certain is that dishonesty is quite common everywhere; forums aren't exceptional. What's the OP's gist?

That's not a bad price for 70 of the large bottles. I noticed that like chocolate boxes in UK have shrunk the bottle size had mostly been cut to 580ml for tsingtao and similar. I don't think you'll get a better price in Northern China- and the tins will be prohibitive. Do you buy the beer in any particular shop? Walmart maybe-they do the large bottle. No you certainly buy your beer cheaply-you won't find an FT buying cheaper beer, that's for sure.
