I should perhaps add a disclaimer about the price. That is, my local shop may not have charged me the full mark-up, me being a "regular." I know he seemed to think the full retail mark-up would be too steep. I told him not to short change himself and charge the proper price but I am not sure if he did or if he did indeed give me some sort of a break. That's why I was being a bit vague about the price.
YMMV as they say.
Not sure if there is a bulk discount...I could try ordering some more and pass them on if people are interested. Might take a while though...
