Coles Online suffered an outage after a system error put alcohol on sale at nearly 80 percent off. A Reddit user posted about the discount and shoppers rushed to buy cases of drinks. The discount was almost 80 percent off the regular price. The site collapsed as traffic spiked sharply. The incident occurred before the company released its earnings update. It came after a weekly market value decline of A$965 million. The Guardian reported the crash and 7NEWS documented the buying spree. TechStock² pointed out the error ahead of the earnings release.
