Tesco and SuperValu have followed rival supermarket Lidl in announcing surprise price cuts to milk.
Lidl announced on Friday that it is cutting the price of a two-litre carton by 10c - from €2.29 to €2.19 - coming into effect from today.
The budget supermarket became the first Irish retailer to reduce the price of milk after many British supermarkets also slashed the price of the product earlier this month.
