Target expanding private-label food

Target is reported to be increasing the square footage devoted to food and expanding its private label food offerings. They've introduced their own meat brand (Sutton & Dodge), increased their premium private label line, and are giving more displays to food.

However, asks the article:

How can a retailer differentiate from Wal-Mart, create a strong brand image, compete on price and be everything to all of its consumers at once? Some say Target doesn’t know the answer quite yet, some say it’s on its way and others banter about whether or not Target knows the right strategy at all. Is the $52.6-million retailer on target?

It's a good article, that attempts to answer these questions (it's lengthy, and excepting it wouldn't do it justice).
