The option of having similar offers like "buy one now get one later" (like Tesco in UK) is more accepted - but on the other hand this might make it harder for the shops themselves to order the right amounts. One example for households is the possibility to buy smaller packaging and the possibilities to buy fresh fruits and vegetables cut in halves (on the contrary today often the packaging size is getting larger and larger making it impossible for a single household to finish the food before it goes bad). Smaller packaging are often today significantly more expensive (cost/ kg) than larger packaging and since the cost/kg always is displayed many people choose the larger packaging just to get cheaper food.
