I just heard the most amazing thing from a Target cashier. I was bemoaning the fact that the MWC Target didn't have a full grocery/Super Target set up to save time and hassle.

She told me that the original plan was the Target store on 29th would be a Super Target, but Midwest City stated that they had a 99 year agreement with Crest to not allow any grocery stores within so many miles of Crest.

Isn't this illegal per the Sherman Act or other case law? Is this even true?
Anyone have any idea? Nothing on Google so far.
