It was the best price seen in New Zealand for tomatoes in 10 years, and Hastings Pak 'n Save customers weren't going to miss out.
The supermarket sold about two tonnes of tomatoes on Wednesday morning alone, with 9 cents a kilogram prices drawing plenty of attention online.
Dozens of people could be seen leaving the supermarket around lunchtime with two big bags full of tomatoes each, including some who hadn't purchased anything else.
Store manager Julian Gibbs said Pak n'Save put a limit of 10 kilograms on individual purchases to be able to offer the one-day only sale of the four tonnes of tomatoes to as many customers as possible.
Tomatoes NZ general manager Helen Barnes said generally supermarket tomato prices only occasionally went below $2 a kilogram.
