For smaller items many people specify their work address as the delivery address. This usually means you would be on hand to collect an item, and that there would be somebody to take delivery at all times. It will depend on what you are buying. Most couriers will require a signature and somebody will need to sign for the delivery. If you opt for postal delivery rather than courier, you will be able to request an alternative delivery date from your postman using the card posted through your door.
Some couriers also offer one additional delivery if the first one misses.
If you find you have a problem with a failed delivery, contact the merchant for advice. For very large items such as electricals or household appliances, you may be phoned to arrange a delivery time, or you can phone to arrange one. This will be no different to arranging a delivery from a store, warehouse, catalogue or by mail order. Remember to discuss installation options.
