OK so go to www.google.ca and type "bakery supply calgary" into the search box.
You don't have to remember the name to find a business. There was one in Western Canada called MJB or MJS or something--maybe that is who you remember?
I'm sorry the BB didn't turn out as good a price as I thought. Their prices for icing sugar are competitive and they carry high-ratio shortening as scoop-your-own instead of you having to buy a huge cube.
The No Frills chain (Weston again) carries the NO NAME yellow packages--cheap but you have to add pudding mix and more water. NO NAME is really good instant pudding, I tried them all and was very pleasantly surprised. Don't know if that works out to the same $$$.
The other place to look is Food Basics (competing chain) or Sobeys/FreshCo or even Wal-Mart (ugh...gasp...I know) because they carry name brands at very competitive prices. The house brand at Sobeys is better than the NO NAME yellow box brand. I don't know if Safeway has a discount chain out west, but their house brand of cake mix is again as good as DH.
