Is it much better to do online grocery shopping than actual shopping in supermarkets?

Pickup and Delivery Slots

Pros: Online ordering usually gives you options of either home delivery, mall locker, or click-and-collect store collection. Most stores specify a two-hour time slot for your grocery delivery or collection; some may narrow it down to just one hour. This makes the service very convenient. With an 18-hour delivery window to choose from, seven days a week, you can easily fit your grocery shopping around your other commitments. Cons: Delivery charges may be higher for the more popular delivery slots, for example on a Friday or Saturday. For major public holidays like Christmas or New Year, delivery slots can get booked up several months in advance. You can avoid excessive delivery charges by booking early and planning your shopping spend weeks ahead.
