Costco Wholesale is known and beloved for its mega-selections of bulk items, food samples, in-store food courts and more. 

Rachel Huynh, however, might be one of the biggest Costco super fans out there.

That's because she celebrated her birthday in true Costco-style. 

NORTH CAROLINA WOMAN CELEBRATES 30TH BIRTHDAY AT COSTCO

Huynh is a 27-year-old immunology PhD student who recently enjoyed some birthday fun with a Costco-themed party at her Portland, Oregon, home.

Her husband, Tony Huynh, told Fox News Digital that the idea for the party came about because of his wife’s huge obsession with the wholesale store.

"Rachel is a huge Costco fan, although she prefers ‘super member,’" he joked. 

He added, "She loves Costco because she loves good deals, buying things in bulk, free samples and the $1.50 hot dogs that come with a soda."

The Portland-based couple said they love all things Costco — and created the custom decorations themselves.

"All of our decorations were made by Rachel using our Cricut and our Canva subscription," Tony Huynh said.

He added that Rachel Huynh became an "avid Cricut user" after their wedding in August 2023 and was able to use her skills for this project. 

"We then printed out photos and signs from our local FedEx … and a few of our friends who are equally big Costco fans helped with setting up the décor, blowing up balloons and setting up Costco-sized samples for the party," Tony Huynh said.

He also said that they turned existing photo frames in their space into Costco quote boards, "Member of the Month" signs and travel boards with photos from places where his wife visited.

Tony Huynh also said his wife replicated the Costco supervisor vest, put price tags around items on their home and made custom employee badges for guests, among other things.

"Our guests loved the Costco Photo Center — our photo booth," he said. 

The couple also noted that Tony Huynh’s sister, Kayla, is actually a Costco employee and helped inspire much of the décor.

Guests at the party played Costco trivia and "guess the price" games with prizes, including a Costco super member tote and a gift card. 

Although the party had no dress code, some of their guests showed up wearing official Costco merchandise, the couple noticed.

Tony Huynh said he and his wife were not expecting the video to go viral the way it has. 

"Our guests loved the Costco Photo Center — our photo booth."

"It’s even more funny how much people identify with how awesome Costco is," he said.
