One of the biggest pop-up businesses in golf is happening this week.
Last year, the U.S. Open sold around 400,000 items over an 11-day stretch.
To make it happen - it is a multi-year planning process.
Here is how it works.
Merchandise preparation begins two to three years before the actual tournament.
It all starts with the logo.
The USGA works with the host club and an internal design team.
One of the primary keys of the logo? How well does it embroider.
The USGA has had prior championships at Pinehurst. They have data to understand what will sell and won't won't.
For example - black and navy don't do as well as other colors.
They take a look at weather and demographics and utilize market research to understand what will sell.
For LACC, they visited pro shops in the area a year in advance to see what colors and styles sold well.
Dozens of USGA employees and interns help in preparing the merch pavilion.
Some will be on-site for months before the event, while others will travel back and forth.
Last year at LACC - they had 20 UPS trailers to warehouse their inventory.
Hundreds of volunteers will assist in the 35,000-square-foot merchandise pavilion.
Merchandise for the U.S. Open is a crucial revenue generator for the USGA.
Other USGA Championships make up about 8% combined of what the U.S. Open does in both items and revenue.
At LACC they sold around 400,000 items - or around 3,000 items per hour.
If you throw out a hypothetical average price of $60 per item. That is $24 million.
Pretty good.
