Before the local Kmart out west usa here closed they used about 4 channels. Ch 1 was main operations. Loss prevention had one, then the other 2 were chit chat or managers time to time.
I lately have seen lowes hardware with the murs vhf rigs wal mart uses so I been meaning to ask someone about the pl and dpl setups and what channels are what
. So far I haven't caught much activity but I do know during xmas sales the channels are key to where a pallet of low quantity item grabs will be placed during the xmas rave and rage.
