I've done all checkout styles and I think the best is scan as you shop with a little handheld scanner is best by far, you can pack as you go along and I think I've had a random check like 3 times in years of doing a weekly shops. I like having a running total and being able to price check, it's mostly fantastic. Only downside is fruit and veg which you have to weigh and print a sticker for, that's about it. In my mind the perfect experience would be a trolley/cart/basket with a screen on it that detects what was inside.
