Within 24 hours, perhaps motivated by the fact that the story did appear on TV, Walmart's corporate office sent additional employees from neighboring stores to this store. No AEDs in stores (automated external defibrillators) Many Walmart stores have no AEDs, which has led to criticism from those who have needed them whilst in their premises.

While Sam Walton was alive, Walmart had a "Buy American" campaign, but it was exposed shortly after he
