A Costco connoisseur has shown her devotion to the budget retailer by holding her birthday party in the food court of one of the cut-price superstores.

The thrifty Floridian, known only as Madison, invited six family members along to her celebration on Sunday evening, filming the festivity for TikTok.

“Today is my birthday, and I’m having my birthday dinner at Costco,” she excitedly announced in a clip that has racked up 2.1 million views.

“This is going to be the cheapest birthday dinner ever,” the blond boasted as she selected food items to eat once she made her way inside the store.

Madison and her group ordered five hot dogs, a chicken bake, a chicken Caesar salad, a whole cheese pizza pie and several sodas, with the bill totaling just $30.88.

The Costco member and her crew were subsequently seen chowing down on their feast at a table set up near the cash registers.

Madison, who boasts more than 6,000 followers on TikTok, is an avowed Costo fan who frequently shares videos advertising the bargains she finds at the franchise.

The content creator, clad in a Costco hoodie for her superstore celebration, also received a freebie from employees during her food court festivities.

“Workers at Costco just came and brought me a free happy birthday cake,” Madison beamed in her viral video. “They came over singing. I was like, ‘Who was singing?’ And they gave me a whole cake. That is so nice.”

Madison later revealed that she and her family also opted to get dessert, acquiring four sundaes and churros for a further $12.97.

“Cheapest and best birthday dinner,” she proudly declared in the caption of her video.

Viewers were wowed by the low cost of the birthday party and told Madison that she may have started a movement.

“You just started a new birthday trend,” one declared.

“My mom’s birthday is 12/14 & I just showed this to her,” another commenter declared. “Now were going to Costco on 12/14.”

“Great reminder that life doesn’t have to be complicated!” another chimed in. “Happy belated birthday.”
