I went to the grocery store today to pick up some last-minute things for my mom and noticed that a few of the General Mills cereals (large-size Coco-Puffs, Lucky Charms, Honey Nut Cheerios) were marked as having a Spider-Man decal inside. The Coco-Puffs were on sale ($3) so I bought a box. Each decal is die-cut on a 4 x 5 inch backing (like the Star Wars: The Force Awakens decals General Mills did a few years ago) and there are 6 different. I think the promotion just started.

Edit:
It promotes the movie, "Spider-Man Into the Spider Verse."

Purcahsed a box of Cinnamon Toast Crunch and I got the Spider-Gwen decal...

I still see these boxes in a couple of stores after it appeared the promotion was over a few weeks ago.

I think I've bought 7 boxes of cereal but got 5 of the same sticker. One local store still has the boxes.
