Definitely down to personal preference, but the milk at our Target is generally in better condition, tastes better, and lasts longer than the milk from Safeway. And the shopping experience in general is much nicer than Safeway.
Safeway is pretty much the bottom-of-the-barrel grocery store in my area, so while I'd agree with that comparison of Safeway to Target, it's less true of Target than just about any competing conventional grocery store.
It's not weird, there's a good reason for it. As I mentioned in a previous comment, its because the milks with a longer shelf life are UHT pasteurized, which uses higher temperatures for a shorter period of time than traditional pasteurization. They are typically labeled "ultra pasteurized." This extends the shelf life of milk.
Additionally, any time you see milk that is shelf stable (doesn't require refrigeration until opened) its been UHT pasteurized and packed in special aseptic packaging.
And, yes, I've noticed that, for some reason, organic milk tends to be UHT pasteurized more often than non-organic milk.
