The news is that Target is retiring its "Merona" brand, presumably soon.
I've recommended their Merona polos before; they're 100% cotton, logo-less, and with tails (the longer back half helps a polo stay tucked in, and the slit between the front and back makes it more comfortable tucked or untucked). They're an amazing value at their usual retail price of about $13, and an insane value on sale (I picked up two more earlier this summer when they were only $7).
My only complaint is inconsistent sizing, so try them on before you buy.
I plan to hit Target in the next few days to see if they're on clearance, and I recommend that everyone else do the same.
Hopefully they'll release another polo at least as good, just under a different name.
