YMMV on this, but I just returned from Oshkosh PNS.

You get 2 milks free with your free milk deal from GM from the last 2 weeks. The catalina is scanning at $3.75. I told the cashier that the milk was only $1.68 and she told me that they were supposed to ring it at $3.75, so if you still have that coupon, might as well get some milk

I posted this on happysoul's blog as well. check that out for other deals today if you havent' already.
