I also picked up a case of Vanilla Coke Zero, while not a "new product" its fairly new on store shelves in WNY.
Also, grabbed this new Ken's salad dressing flavor at Wegman's. If you shop in the US and have never tried the Ken's products, try them they are great. I tried this in Chicago a few weeks ago and just had to pick some up.
My trip two weeks ago to Michigan I did a Costco run, and picked up a few favorites that I highly recommend. The pickles especially are a deal, its a massive jar Costco style and dirt cheap, these things taste so good.
Famous Dave's Pickle Chips
The deep dish pizza, I wish Costco would carry this in Canada, is actually really good and dirt cheap its 3lbs of pizza, the family loves it.
Texas Caviar bean salad, its gluten free too. In fact Coscto in the US seems to have a good gluten free selection.
