The discounts run until the end of May, with a specific items discounted on the different days of the week. Monday is fish-day with a 30% discount on fish, Tuesday meat-day, followed by cheese-day, veggie-day, ready-meal-day and finally bread-day on Saturday when bread is off 30%.
Marqt is fun to go to with its market-style set-up and focus on fresh, local produce. But it also suffers from limited selection on several product categories and high prices on others.
I like the fish and the bread. So if you want to take advantage of the discounts, check in on Monday or Saturday.
