Attention, the purchase total is not quite as easy to determine as it may sound at first glance.
Please bear in mind that there are various circumstances that can make it extremely difficult to determine a list total: * Various promotions and different promotion conditions (prices, quantities) * Regional differences * Combinations of the various price-determining factors * etc.
You would then also have to be able to enter where you intend to buy and when. There are people who live in the border area of two cooperatives (GM1 and GM2) and there may be different prices for the same product. Or a product is not available in GM2, while it is currently on sale in GM1.
Even within the same GM: depending on the layout and store size, some products are not available in all stores.
