MyPillow CEO Mike Lindell says Costco has pulled his products. It's the second-largest retailer to cut ties with him.

• Costco has stopped stocking MyPillow's products, MyPillow CEO Mike Lindell told Insider.
• Retailers have cut ties with the pillow brand after Lindell spread voter-fraud conspiracy theories.
• Lindell blamed Costco's decision on "cancel culture."

Costco is the latest retailer to cut ties with MyPillow, according to the pillow company's CEO, Mike Lindell.

The big-box store stopped stocking MyPillow's products without telling the pillow company about the decision, Lindell told Insider in a phone interview Monday.

Major retailers have been severing ties with MyPillow after Lindell, a staunch ally of former President Donald Trump, spread voter-fraud conspiracy theories. Some of the retailers have cited slow sales.

Costco is the second-largest retailer, behind Kroger, to stop selling MyPillow products. Costco sold out its MyPillow inventory and then stopped ordering new shipments, Lindell told Insider.

He blamed the move on "cancel culture."

Insider reported on Saturday that MyPillow's products had disappeared from Costco's site. At the time, the company wouldn't say whether it had pulled the brand.

Costco did not immediately respond to a request for comment on Tuesday.

Lindell previously told Insider that at least 22 retailers had pulled his company's products since January, including Sam's Club, Kohl's, and Bed Bath & Beyond.

More than 100,000 people have also signed a petition calling on other retailers, including Amazon and Walmart, to follow suit and stop selling MyPillow's products.

Lindell said he expected the drop in retail sales to cost the company about $65 million in lost revenue this year but that radio and podcast infomercials could plug the gap.

During an appearance on "The Domenick Nati Show" in mid-March, Lindell said retailers who cited slow sales for cutting ties were "lying" and were "big losers."

He said calls for retailers to stop selling his products came from bots and trolls, adding that the companies who kept stocking MyPillow were "thriving."

Lindell added that lots of customers had been buying directly through MyPillow and that it had to hire more staff to meet demand.
