Lurpak butter and its dupes have increased in price over the last year.
Aldi, Lidl and Morrisons all have their own-brand equivalent of Lurpak. Aldi sells Nordpak, Lidl offers Danpak and Morrisons stock Spreadable.
Customers have begun shopping for cheaper alternatives after noticing last year that Lurpak was being sold for as much as £7.50.
