I buy 8oz bags for $40. That's $5 an oz, and a tin of anything else would be about $6-8 an oz. So, Penzance is priced at a value, IMO. But, some buy it on ebay at much higher. But, that's their prerogative. I find that being patient fits my budget better.
But, a little birdie told me just an hour ago that this blend may become less hard to get... after the hoarders have done pillaging the market soon. It has slowly been becoming available at closer intervals, so maybe this birdie knows something, maybe he just a damned ol' bird. We'll see...
