Some of us do not have a choice. Dietary issues prohibit the consumption of cow's milk. I am not a fan of Soy milk, can't consume cow's milk, nor oat milk, only leaves me with almond milk - plenty of brands on the market.
Each to his own - a label maker is restricted in font size, I know, I have one, yes they are tidy, however labels cost. A chalk marker is an alternative, and personally, I quite like the hand written labels, gives a personal touch :)
Great tip. I sometimes forget my bags or leave them in the car, in which case, I put everything back into the trolley and bag my groceries at my car boot - I have more than enough bags.
