It's like the old BCS, except the 2.0 makes it fancy. Wondering why you can't post here? Check out the rules and expectations, and it all should be made clear...
Typos happen, especially for a small item. More surprised to see something like that in a flyer. The price doesn't reflect what's on Walmart.com or the store, so, most likely the 2 is the issue. Several Walmart stores have several sets on rollback right now, so someone just did a copy/paste and messed it up.
You know, if I see links to Brickshelf, more often than not, the first thing I click is the "Back" button.
