Ummmm, at the sake of not offending loyal shoppers, I will plead the fif.
I realize that morality/ethics can be comprimised when a store is trying to keep the doors open in a bad economy, but these LFS's make Petco look like a PETA Sponsor.
I am certain that none of them would have a problem with labeling tap water mix as RO/DI Salt and selling it to newbies without a TDS meter.
This would be a great piece for local news to do.....go into these shops, buy a gallon and go into the parking lot and test it to reveal the scammers.
I know of soooo many horror stories from this store bought crap....people put confidence in it.
