Could be a possible sign of future things from the retailer as Walmart decided they wanted to get in on the amibo scalping market with the Marth amiibo as a possible start. They got a new shipment of the figurine recently and deiced to hike the price to $28 each.
Ended up selling out almost as quickly as the first batch of the figurine.
