No f'cking different. That only applies to food that you take on the day it is put on sale unless you think they stock the food daily, throwing away any unsold food at the end of the day? Don’t be daft. What about food that is, say, put out on Wednesday and still there when you turn up on Friday to do your shop? Dunno about you, but I always pick my food from the back of the shelf or even from the bottom tray. A day here or there is no big deal - if I don’t think it will last until I use it, I don’t buy it. It’s as simple as that and imported food could have a longer shelf life than home produced depending on when you buy it. We're not forced to buy anything just because it’s on the shelf. Stop making up imaginary scenarios. Are you sure you're not DiyNutJob on the quiet?
