I am particularly well aquainted with two branches of Tesco-one with a nearby Lidl one without.And guess which one always has the cheaper brands on offer? And now figure which one advertises-but doesn`t always have the cheaper brand available and worse still doesn`t advertise and never stocks certain other cheaper items.
I don`t know if my source is correct. Maybe there`s only two pricing brands-cheapish, and Irish. But I know that Tesco, wisely, will compete if there`s competition within their local territory. And I`m glad Lidl and Aldi have also brought about that.
