For certain express items, you can request that they be delivered on the same day or the next day if that was not their original delivery estimate. Please note that it is not available for all express items.
You'll see a banner on the product's description page that lets you know whether an item is available for same day delivery or for next day delivery. Please note that both options cannot be available at the same time.
At checkout, you'll be able to select same day or next day delivery as an option which will then apply to eligible express items in your cart. Upon selection, a fixed price fee will be applied.
