Hi,
@belleincanada,
Amazon Prime Pantry is $5.99 (for two-day delivery) per shipment and focuses on cereal, vitimins, laundry detergent. Delivery is normally two days. Included with your Amazon Prime membership.
Amazon Prime Now is free (for two-hour delivery) and (IMO) focuses on things in your day-to-day life that you may need quickly. They have power cords, chargers, milk, toothpaste, yogurt, some books. Included with your Amazon Prime membership.
Amazon Fresh is an additional $299/year (for either same-day or 24-hour delivery) and focuses on fresh items--like fruits and veggies.
If you have Amazon Prime, the Amazon Prime Now is a good option.
