Old El Paso BLASTED Shells - Where to find them?

Does anyone know where I can buy Old El Paso Stand'N'Stuff Blasted Shells in Ontario? I've tried a Metro, a Loblaws, and a Sobeys, but no luck.
I believe I got the coupon for them (buy any Old El Paso Shells, get Blasted Shells free) from the Walmart portal, so does that mean Walmart will have them for sure?

Thanks

Walmart has had the cheese ones for a while.

Think I saw some recently at Fresh Co as well.

Thanks for the info @annedougherty and @sweetmomma :)

Sobeys had them a few months ago. May still carry them

Thanks, friends. I got some at Walmart today.
