Unfortunately no, Dell does not sell replacement monitor or PC boxes. You will have to check with local moving business for a suitable box and packaging material.
Hi there!I'm anticipating moving overseas in 3 months. With that, I'd like to bring my two monitors (S2721DGF) with me rather than buying new ones overseas. From my understanding and research, the absolute best way to do this is by using the original boxes they came in which I no longer have. Would it be possible to receive replacement boxes or is that not a service offered?Thanks!
