Sorry Dave, but I totally disagree. Let's not forget the average Petco is heavily setup to sell freshwater fish and products. For example, rarely do you see skimmers, but you see a ton of power filters and canister filters. Every color, including glow in the dark gravel and artificial plants, yet maybe a small bag or two of aragonite. The majority of their fish runs house freshwater fish. They're really, in terms of aquatics, setup up for freshwater and NOBODY is complaining about that. It's the small fish run with no separate qt, untrained employees that we have a problem with as they kill more fish than they sell. My local Petco finally stopped carrying marine livestock because they were killing $500 a week worth of fish and inverts. I applaud them for making the decision not to continue that insanity. And if every Petco followed suite they wouldn't get blasted on here all the time.
So to clarify, it's not that everyone hates Petco, we hate that they don't take their marine life section serious. Also, buying a tank at their $1/ gallon sale does not support them at all. They are not making any money off that sale. I don't know for sure, but they are likely buying those tanks at cost or taking a small loss and hoping you will buy everything else needed so they can turn a profit on substrate, heaters, filters, decorations, lights, food and freshwater fish. I'd also imagine the majority of the $1/ gallon sales are people setting up freshwater tanks.
So again, we don't hate Petco, we hate that they sell marine life. If they stop that, you wouldn't see the constant bashing anymore.
