This is the lowest per-serving price you can get anywhere.
Brad's Deals Editor Marisa,
This Kraft Easy Mac 18-Count Pack is $5.98 right now at Amazon. Walmart has matched the price, but this is the best deal you can get on it. Compare to Target where a six-pack box is $3.19. To get an 18-pack, you'd spend over $9! Prime members will get free shipping. Non-members can spend $25 to get free shipping. Otherwise, it adds $5.99. Sales tax is charged in most states.
