A can of mackerel was on sale at Countdown this weekend for $7.
The Tai-Yo 425g can of mackerel in tomato sauce was on sale at the Auckland shop next to a different brand on sale for $2.50 or $2.20 for loyalty card holders.
The price visibly startled some shoppers - but is not necessarily due to any inflation or supply chain issues.
“The Tai-Yo Mackerel product you refer to is a premium fish product, imported from Japan and new to Countdown,” the retailer said.
Its shelf price reflected the cost from the supplier, Countdown said.
