The entry point is pretty much here now. The stock will float up and down while we have this low volume and uncertainty. When a business is valued it is a sum of all it's current value and it's potential future value. The current foot print won't allow for a share price much lower than it in my opinion. I brought the dip yesterday even though it raised my average cost a tad.
BTW IP is completely correct on the COGS. Anyone who has owned a business knows the 'Art' of taxes.
