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

Save Money With Virtual Shopping

Pros: Shopping online means that you have saved spending money on gas and parking charges. You will have time to browse all the special offers as you put your grocery order together. You may wish to check the price of big-value items on a comparison grocery shopping website. The comparison sites monitor online and offline grocery prices. They can save you the effort of visiting all the individual grocery sites yourself.Cons: Popular offers may sell out before your allotted delivery time. Even though the supermarket will bring a substitute, you may not like it, which can lead to disappointment.
