have had a response:
"
Unfortunately air doesn't bode well in jars, the screw top lids don't seal it in properly, and they tend to smash during transit. I have had many letters of complaint from the Japanese before i corrected this issue, however, I could send you a bag with some in it, but I can't guarentee its freshness, as i only make 3 trips a year to Nevis each month, and as you know, the wild haggis have a dislike for air takers at this time of year, being breeding season and all. They have a nasty bite if you get on the wrong side of them."
hee hee!
If I had a spare 99p I'd buy some just for the larf!
