I did it! I'm fiddling while Rome is burning!
So the Brooklyn Target did not have the sale listed, but they do price matching with the website. I had to go to the "service" desk and wait in line for 20 minutes while people tried to return opened paper towels and whatnot, but I eventually bought the console at the $239.99 price. I consider this okay because if Nintendo does a discount, I suspect it will be to a $300 consolidated SKU with most of the deluxe features, so this target deal will still have been worth it. If they drop the basic to $250 in the fall or something, then, eh, still ten bucks cheaper and months with the unit.
Picked up NSMBU and AC III, which was on sale for $30 and hard to say no to. This was actually the cheapest Wii U game they had. If anyone wants in on that, I recommend checking out your local target.
