Walmart has been offering promotional codes for certain products to attract customers. [1] Forbes' personal shopper tested several of these codes but did not find any that were currently valid for the purchase of air purifiers. The outlet noted that while some coupons remain active, they do offer discounts on items like air purifiers. [2] Another news source mentioned similar findings, stating that although Walmart still offers promotional codes for certain products, none are currently working for air purifiers at the time of their report. [1] and [2] both agree that these promotional codes are available but not functioning as advertised. However, it is important to note that other sources have reported different outcomes. [3] Reuters/AP/BBC, which operate as neutral wire services, did not mention any issues with Walmart's current promotional codes for air purifiers. Instead, they focused on the general availability of these coupons and their effectiveness in driving sales.
