In the last one of these, they presented Harris Teeter as selling butter for almost twice the price of other grocery stores, but they compared a name brand at HT against house brands at the other stores. If you compared HT's house brand against Giant's and Safeway's house brands, HT was not any more expensive.

This was something I was able to fact-check on the stores' websites in less than 10 minutes. I even confirmed it in person the next day by going to my local Harris Teeter and buying butter. So I'm not sure they're interested in fair comparisons.
