Most places calculate and charge for fractional BF. First ripoff
Edge ripping 11%. never heard of that either. Ripoff #2
An if there's significant sapwood, cracked ends or otherwise unuseable
parts, they subtract some BF
Kiln shrinkage. Never heard of "shrinkage", not that kind anyway...
ripoff #3

Anyway the base $/BF seem OK, but all those "extras"
