I have to say that a grocery "store" I have been using a lot in the past few years (more specifically, about 150 times - they put your number of orders on the invoice!) is Grocery Gateway, owned by Longos, of course. I have had very few problems with them over the years, and all have been resolved to my satisfaction. The drivers are never late, the produce and meat are top quality and it is incredibly convenient when you're busy, don't own a car and generally couldn't be bothered with the crowds at your local store (in my case, it's the Metro at Yonge and College).
