Local dairy farmers continued their protest about milk prices at three local supermarkets on Monday evening.
The farmers gathered at Sainburys, Asda and Tesco in Coleraine.
They say the price of milk is too low for them to make a living.
After taking supermarket trolleys into the store, the farmers surrounded the milk fridge in an attempt to let shoppers know how their incomes have fallen.
They are being paid 10p a litre less this year than last.
Police and supermarket management took a low-key approach during the protests - as long as shop business was not disrupted the protests were allowed to continue.
