I've gotten the Summer and Spring bags, and now this one, too. Sad it's the last one, but I have a feeling it's because the Target Style page gets FLOODED with wall posts questioning when the next bag is going to be. They keep saying that they're not a freebie/sample page, so I have a feeling they're trying to return the page to its "roots," as it were. Just a theory.
Yeah, if you look at the terms and conditions, you'll see what the items are.
It's not always the same as the picture (I feel like the Spring bag was different!), but if I remember correctly, it is the same this year.
Warning: the Pixi Primer will most likely just be a small blister sample (i.e: on a card.) That's how the makeup items have always been. ...shampoo/conditioner are usually "deluxe" sized, though, and I know in the past the Aveeno scrub was, as well as the Neutrogena Sun Block from Spring and Summer. So yes. But remember, it's free!=)
