It’s beginning to look a lot like Cringe-mas.

A lifehack-tivist is being dragged online as a “horrible person” after promoting a controversial method of scoring a free Christmas tree in a popular TikTok video.

In a five second clip that has already racked up more than quarter of a million vies, Mai, of the duo Mason & Mai, can be seen striding confidently through an unnamed store and picking up a boxed artificial tree from the shelves, before turning around and walking away — all to the tune of “It’s Beginning to Look a Lot Like Christmas.”

The Australian pair, who post under the handle @savingforboba, regularly share quirky and humorous tips and tricks for cheaper and better living — everything from scoring free chips to telling if Chinese food is going to be bad.

For their latest shortcut, or hack, Mai described how she avoids paying for Christmas trees — simply by buying and then returning her faux fir, within the store’s “30 day return policy.”

The majority of viewers were not impressed with Mai’s tricky tree-cycling program.

“You are a horrible person,” declared one critic, while another wrote, “You’re one of the reasons prices are so high.”

A third fumed, “Now you know why those who work retail have bad attitudes, because of pieces of s–t like you!”

Some viewers even labelled the money-saving method unnecessary, given the low, amortized cost of a synthetic evergreen that can last in one household for years.

One armchair environmentalist dubbed the influencer’s idea “wasteful overconsumption — as “most returned items aren’t resold.”

Meanwhile, many thought Mai’s video was a “joke,” given that many stores don’t allow returns on seasonal items, especially after the holiday.

“Most places don’t allow these type of items to be returned after Christmas,” said one commenter.

Another wrote, “Most holiday stuff is final sale to begin with. Guess it depends on the store but the ones I worked out there were no returns.”

The Post reached out to Mason & Mai for comment.

Yuletide return policies vary. Walgreens, for one, doesn’t permit returns on seasonal items, including Christmas trees, a store representative told the Post.

Target offers a 90-day return policy with certain stipulations, so technically one could employ Mai’s complimen-tree tactic there. Still, the store warns that “holiday and limited time only collections” may have modified policies — best to ask before buying, if you’re depending on getting your money back.

Meanwhile, many online bazaars, including Amazon and Wayfair, tend to offer generous return windows — often at no extra charge.
