You assume too damn much.
I don't have a Trader Joe's or the other place you mentioned. I cannot afford to order my groceries from various on-line sites and pay the fricking shipping. I have finite resources and you piss me off when you go assuming that people just do this and that and the other. I live in the heartland and we don't necessarily have the same damn things available that you do where you live. I order on-line from HyVee once a week and drive up and they put the groceries in my trunk. I am limited to what THEY have and they don't have a lot of shit. And a lot of low-sodium crap out there are second rate foods and many of them have simply reduced the sodium and paid not one damn iota of attention to flavor. You're acting like an idiot.
