-(이)라도 marks the purchase as the least you could have done rather than the ideal thing: 우리가 꽃이라도 사와가지고 (we should at least have brought flowers), 제가 죽이라도 사올까요? (shall I at least get you some porridge?). It also covers settling for a substitute — 일본 된장이라도 사왔어요, Korean doenjang being impossible to find, so Japanese miso it was. Several of these lines carry a note of self-reproach about not having done more.
