It's temporarily out of stock but I noticed that Animal Crossing New Leaf is back down to $30 through Amazon. Not quite as good as last week when they kept matching Walmart's random drops but $30 isn't bad if you missed out of it and still looking for it. You have to select it from more buying choices but can still order it for delivery when it's restocked.
