Suggestions for low-priced sources of baking ingredients

[chromedome]

Forgive me if this has been covered elsewhere, but I haven't found a dedicated thread after searching the site. 

 

As I've mentioned from time to time, I'm a freelance writer, and one of the clients I write for currently has an assignment that's mine if I want it. It's looking for 6-10 good sources for "baking supplies on a budget," and of course it's for a US audience while I'm here in Canada. So I thought I'd canvass the collective eG wisdom, and see what suggestions everyone has. Either general responses (ie "check if your local mill will sell directly") or specific vendors would be helpful; and I'm also open to either full-spectrum (everything you need) or single-niche (ie, chocolate, flour) sellers. 

This isn't life-or-death, so no immediate timeline (I have other work to do right now, and one of the other eligible writers may choose to have a go at it in the interim), but it doesn't hurt to ask.

During the banking epidemic, which took place during the...well...pandemic, I purchased from this outfit:

There's also webstaurant store...https://www.webstaurantstore.com/44035/wholesale-baking-ingredients.html

 

In both the above cases, I think buying in bulk offers the greatest savings.
