Today, Jochanan and Lirim went to Baden to ask people on how often they go shopping in general. With that kind of information we are now able to calculate an approximate percentage of savings compared CH/DE. The problem was because it was during the week, the interviewed people were mostly larger families (two kids or more). So it was hard to find people without children or singles.
As a solution, we asked our friends and relatives for their shopping attitude. What we gathered from our questionnaire was that families go shopping more frequently in average once a week for big grocery shopping. And singles go on a big shopping-spree every other week.
We also asked what kind of products are always on their shopping lists and in what amounts. The majority bought an average amount of 4-5 litres of milk per head per week, 150g of pasta per head per week, 150g of rice per head per week, package of ten eggs per week which were mostly battery farmed eggs.
On items like potatoes or other vegetables, we didn't get exact numbers because the amount would vary a lot. We had a problem with measuring the amount of bread consumed, because the individuals like to buy the bread the night before, so that it's fresh.
In the meantime Primo is still in Shanghai.
