Briar Fox, Night Train, and Pirate Kake (and any other "Kakes") are considered "tinned" - not bulk- by Smokingpipes, even though they come as a shrink-wrapped brick. That's why the prices on those were higher last month; Smokingpipes's sale last month was only on bulk.
P&C's sale is on both bulk and tinned C&D tobacco, so if you loaded up on bulk last month, it is a great opportunity to grab some tins on the cheap.
