Pantry Storage containers?

Some suggestions to try: Russell Hendrix restaurant supply, Wholesale Club and Costco Business Centre. Nothing in Canada is going to beat the prices from Webstaurant. I bought my 22 qt Cambro containers at a local restaurant supply place years ago for under 20 (lids were extra) but they've gone up considerably since. These are great for storing rice, sugar and flour. The transparent/whitish ones are cheaper than the clear. Wholesale Club has sets of the smaller containers (2-3 per pack depending on size) and lids are included. Check online for prices and availability (use the search terms "food storage" because Cambro doesn't bring up much).

Rubbermaid also makes a line of commercial food storage containers but I find their lids are hard to snap in place. I use the largest OXO pop containers for flour and sugar in the kitchen. The Cambro containers are kept in the pantry in the basement.

ikea has a whole lineup of small to xlarge storage ... all sorts
they also stack up on each other

I use 48 cup Komax that are available on amazon.ca. They are designed for large quantities of flour or food supply and are leakproof. I use them to store my cigars at particular humidity. Not sure if you'll like the price but worth a look.
