These Black Friday shoppers are seeing red.

Walmart customers were left fuming after finding out Kraft’s new limited-edition “Mac Friday Box” had sold out in seconds.

The novelty item, designed to look like a 65-inch flat-screen, featured 65 boxes of classic Kraft Mac & Cheese inside and went on sale via the Walmart website at midnight Friday.

It retailed for $19.37, a nod to the year that Kraft was founded, with savvy shoppers enticed by the bargain price.

The low cost meant that each box inside equated to less than 30 cents — less than a quarter of the regular sale price.

Others were enticed by the novelty of the product, which was promoted ahead of time by social media influencers, including Zach Ciampa, who runs the account “Snack with Zach”.

Many eager customers claimed they spent hours waiting on the Walmart website ahead of time so that they could quickly add the item to their carts.

However, they were left devastated after realizing they simply weren’t fast enough.

“I literally had it in my cart and it sold out while I was hitting the finish button — what even,” one annoyed online shopper snapped.

“I’m so sad, stayed up for this and I literally have to work tomorrow,” another commiserated.

“Sounds like no one in the comment section even got a chance to buy one,” a third fumed. “It’s prob going to resell for hundreds more.”

As of Friday morning, a link to the item on the Walmart website results in a message that states “We couldn’t find this page.”
