I’m seeing this more and more. People confusing “aisle” and “isle”. Example: “Every time I go to the grocery store I have to visit the isle with the BBQ sauce.” (This is not the only example. Only the most recent. And it’s different people.)

I am fairly certain that your grocery store does not have isles.

Homophone confusion. Grr.
