I'm hoping in a year's time when we are still discounting milk hard that (the supermarkets) are compelled to really dig in - they are just ripping people off and it's just bad business."
Shelves had to be constantly refilled yesterday to keep up with demand at all six stores and Mr Beuvink was expecting the trucks in early today to restock.
"The guys at Goodman Fielder who supply us have just been brilliant. The guys who look after us are coming in twice a day to make sure we can satisfy all the customers are coming in."
Mr Beuvink said he sold thousands of bottles of milk yesterday, giving him confidence smaller retailers could force supermarkets to chance their stance and drop their prices too.
"We are not a big player in the market place so if we can get those sorts of volumes...I just hope other smaller retailers chip in because I'd rather the customer goes and supports the smaller retailer and forsakes the supermarkets who have been ripping them off for ages."
And it appears other smaller stores are following suit, while some have already been offering cheap milk.
The store manager for discount supermarket Urban Surplus, Vanessa Terewi, said the Papakura outlet has been selling two-litre milk for $2, supplied by Goodman Fielder, since it opened about three weeks ago.
A smaller supplier had declined to supply milk to sell at a discount, she said.
"(They) won't supply us because we didn't agree to sell their milk at $2.90. It [discounting] undermines their pricing structure."
A recent Herald survey found that the price of milk was higher in New Zealand than in Australia, the United States and Britain - despite some studies showing we have the lowest cost of production.
