I have always thought of this as more of a growth candidate and it can still be one depending on the final outcome of purchase decisions, the degree of success with the small chains, the profitability of the service network, and possible future aquisitions.
I did not realize that BTN is firmly in value territory as you point out. Here are some numbers.
Book value - $2.98 Tangible book value - $2.69 Cash and ARS per share -$1.2
That should at least provide support as selling subsides.
