Donald Trump’s online campaign shop is joining the Black Friday madness.

The president-elect’s campaign is cashing in on the busy shopping day by offering 30 percent off his “Make America Great Again” gear, according to an email blast sent Friday.

But to score a bargain on The Donald’s retail goodies — including caps, foam fingers and buttons — buyers are required to enter their employer and occupation on the shop’s website.

A Trump spokeswoman said the information would be used for future fundraising.

“That information is required for all political fundraising,” said spokeswoman Hope Hicks.

To tap into the sale, Trump fans must enter the coupon code BLACKFRIDAY, along with credit card and email information.

Trump “apparel” up for grabs on the online shop include T-shirts that read “#BuildTheWall and #BigLeague. On Wednesday, the campaign rolled out a $149 Christmas red and gold ornament with the slogan “Make America Great Again.”

The Trump campaign had $16 million cash on hand and was $2.1 million in debt in the final weeks of the race, according to TheHill.com.
