Pretty much not for me. I both have a bunch of products imported from receipts over the years, and I remember many per 100g prices for products I regularly buy.

Pretty much not for me. I both have a bunch of products imported from receipts over the years, and I remember many per 100g prices for products I regularly buy. This simply does not happen, at least not at the stores I shop for the products I buy (note that I don’t buy any finished meals or processed food outside the occasional salami, so my habits are pretty different from most people).
