We fought a little when the prices went up to $4 and above and sure enough, the prices dropped rather precipitously to the low $3’s. But did we demand more? Nope….and sure enough the prices started back up again, above $3.50…..now above $3.70 and what are we sheep saying? “Well, at least it’s not back to $4.”
