I wasn't home / collection / redelivery

The local carrier will leave a card, retry, leave it with a neighbour where safe, or take it to a pickup point — the options depend on the carrier and country, and they are on the carrier's website under the local tracking number (Tracking my order). Act quickly: most carriers hold parcels 2–7 days, then return them to the sender, after which the parcel can't be recovered and you'll need to contact the store for a reshipment. Make sure the store has your phone number and email; carriers use them for notifications.
