Walmart clearance is extremely YMMV. Good luck replicating this deal.
No doubt. Not posting this to troll the original poster, but I think each store, and each department in the store, is pretty much an independent entity. Dept managers have a lot of latitude about what they stock, when they take markdowns (which reflects poorly on them when they do), etc. This is why a Walmart near me stll has ps2 2004 nba game on the shelf for $40 to this day. Pretty much all deals (unless they are corp driven promotions, like bf ads) are pretty much one-off events, especially blow-out clearance stuff.
