The country store in Stanwood? Any idea on price?

Yep, that's it. Don't remember what the $ was. I keep it in an aluminum trash can lined with plastic yard bag, in the garage, no problems so far.
Don't buy the small boxes of it, just ask them to order a 25lb bag, lasts longer and is a better bargain. Remember...FOOD..grade DM

How do you apply the dust, jersey?

Usually twice in spring, before it gets really hot. Then the fall too when weather is cooling. Mask-up and scatter it around, I don't have the right tools, but seems to work OK.

Thanks, Jersey.

You may also want to check out any homebrewer supply stores near you. I'm not sure how common it is at the homebrew scale, but at the brewery where I used to work, they used DE in the big beer filters.

Heck, if there's a smaller brewery near you, you might even be able to get their used DE for next to nothing.
