Thanks OP for polling! I strongly suggest that when Costco tests ethinic food in Vancouver, Toronto or Edmonton, please add a couple Ottawa warehouses to the list as well. We have the purchase power to prove it!
Others to add:
葱油饼, 冷冻
Duck Confit
Used to buy all the time, been out of stock for quite a while.
Lobster raviolli
Been out of stock for a while now.
Quaker Harvest Crunch granola bar, 18/box
Been out of stock for a month? Heard it was back in store, will check out this weekend.
Nescafe Taster's Choice instant coffee
Hate the taste in the new cylinder package. When I saw the U.S. store still carried the old tub package, I stocked quite a few. But you might want to alert the buyer here in Canada.
