I got a bunch of stuff from Target and my kids were thrilled. Even got a full box of the characters - which I think look better than those in the boxed sets. I personally hate how there are no instructions but we built everything - except the large bowser castle - just by looking at the box images.
I'm very nostalgic with Mario / Nintendo as I grew up with it in the 80's, but these sets, to me, are just odd with regards to role-playing, so we'll be building a moc style something.
Walmart has nothing here, no stickers, or otherwise.
Oh, and the box of figures - lots of repeats, no ghosts.
