(NEXSTAR) – Amazon will be closing its charity program, AmazonSmile, in the coming weeks in order to “focus its philanthropic giving to programs with greater impact.”

In a letter sent to AmazonSmile customers Wednesday, Amazon explained the program “has not grown to create the impact that we had originally hoped.”

“With so many eligible organizations—more than 1 million globally—our ability to have an impact was often spread too thin,” Amazon wrote.

AmazonSmile was launched in 2013. Through the program, Amazon would donate 0.5% of the price of eligible purchases to the shopper’s charitable organization of their choice. According to AmazonSmile’s website, over 1 million charities have received $400 million through the program.

A spokesperson tells Nexstar that the average annual donation has been less than $230.

Amazon now plans to “wind down” AmazonSmile by February 20, 2023.

“We will continue to pursue and invest in other areas where we’ve seen we can make meaningful change—from building affordable housing to providing access to computer science education for students in underserved communities to using our logistics infrastructure and technology to assist broad communities impacted by natural disasters,” the company said.

Those charities that will be impacted by AmazonSmile coming to an end will receive a one-time donation worth three months of what they received in 2022, Amazon explained. Charities will still be able to receive donations until the program officially ends.

After AmazonSmile ends, Amazon said charities can still create wish lists that customers can shop to support the organization.

The announcement comes as Amazon has begun its largest round of layoffs, impacting roughly 18,000 employees.

“Amazon has weathered uncertain and difficult economies in the past, and we will continue to do so,” CEO Andy Jassy said in a message to employees earlier this month. “These changes will help us pursue our long-term opportunities with a stronger cost structure.”
