Are you sure there aren't multiple variations of the same product?

I made an online purchase for some oral-b toothbrush heads from Target. The item that arrived did not resemble what was on their website. I figure since it's a big retailer, it's probably legit. I checked the official manufacturer's website and the product was also different. Digging a bit deeper into the product images, I finally found one that looked like the version I had.
