You don't get the quality of food that you'd choose yourself, when its delivered.
Woolworths have the same item (my experience with dry ginger) one price on one shelf, and another price in, different shelf around the corner.
If you choose the cheaper price, they will charge you the most expensive price. Twice (different items) I've queried the price at the checkout, told
them where I got it from, they checked the price ......guess what I was right. I was told it must just be an old price, but the person was very embarrassed.
