Absolutely. Customers can edit all existing orders (including adding items) up until the usual cutoff time – 12noon the day before delivery.
To add items to an existing order, add the items to your cart and at checkout select the same date as the order you would like to add them to.
To check the date of or edit an upcoming order, simply go to the My Orders tab when logged in.
Swapping between a Food Host and home delivery is also possible here, noting that any delivery fees will be adjusted accordingly.
