Hi Norm,
They're not that expensive at all, if I recall correctly a box of 12 is around $74.00 from the distributor direct to you.
Because of the issues that I had with them, they just sent me a box full free of charge, but to be brutally honest I think they just want to get rid of the aging stock they've got on hand as it gave Bon_Scott heaps of grief and then me as well.
Like I suggested above if you leave the can out in the sun for a hour or so on a warm day it seems to function better than being stone cold in the tin.
Cheers,
BB.
