The kids hate it, it's more difficult to do it with them (for many reasons varying with age). Why not do it online (unless they don't deliver to your area- does this happen?) it's quicker to do it online once you've set it up. It's cheaper- as you don't tend to browse and buy crap so easily. And there is no crying/moaning/complaining children to drag along. You don't even have to load stuff excess times. Ie from shelf to cashier belt to bags to car to driveway to kitchen. No brainer really?
