Costco is seeing red after a Thanksgiving Day computer foul-up tanked an estimated $11 million in sales for the warehouse retailer.
The site was down for at least 16 hours on Thursday, Business Insider reported, citing the outage-tracking website Downdetector.
Shoppers griped on Twitter that they were unable to spend money.
“#Costco I am literally trying to give you thousands of dollars (since 10am), but your website won’t allow,” user @MurraryMagic82 tweeted.
Another user joked “Hey #Costco, maybe try turning it off and on again?! Just a thought…”
The retailer did add an alert to its site about “slow response times” and said it would extend Thanksgiving Day promotions into Black Friday “while supplies last.”
A Costco representative did not respond to a request for comment.
