Coming from Toronto, I've found EVERYTHING in Calgary more expensive. But I've never seen anything like Sunterra before in my life - and I've shopped at Pusateri's and Bruno's and Summerhill Market.
Assessment: A good but insanely expensive meat counter and deli, a mediocre selection of insanely expensive shelf goods, a nice little bakery that actually isn't too stupidly priced for the quality, a piss-poor selection of too-often past-its-prime produce at prepare-for-the-apocalypse prices, and last but not least, ready-prepared meals that I can charitably describe as second rate - that they describe as "gourmet" and "feasts", and mark-up by 500 to 700% by my estimates.
These guys have the biggest cojones in the country.
