Skip one delivery with the Skip button under it in My Viva: no box, no charge, and you can restore it until its cut-off. Use Skip when you know the dates, for example no delivery this Sunday.
Pause from Your plan when you’ll be away longer or don’t know when you’ll be back; your subscription waits, with no charges, until you reactivate from the same screen.
Both are free and both respect the cut-off: a delivery already past 12:00, three days before, still goes ahead.
