Obama was seen browsing through crew neck sweaters for his daughters and wife as he made a pitch for increasing minimum wage.
"I’m here at the Gap because it never hurts to bring something back home -- I get points,” he joked as he sifted through garments in front of around 20 surprised customers.
The President went on to congratulate the retailer for its new policy of paying entry level employees more than the minimum wage.
"It's not only good for them and their families, it's also good for the entire economy," Obama said. "I want to congratulate the Gap for doing the right thing."
For months Obama has been urging Congress to approve an increase in the minimum wage from $7.25 to $10.10. During his visit to the Gap he pointed out that the average minimum-wage earners are not teenagers but people in their mid-thirties.
According to the New York Daily News, the president paid $154.85 for his purchase, which consisted of two button-down sweaters for his daughters -- one coral and one pink -- and a light blue workout jacket for Michelle.
Humberto Ayala, the store's general manager, said the president joked about "about not wanting to pick out pants sizes for his wife and daughters."
"I think the ladies will be impressed by my style sense," Obama said.
