I clicked through the forum posts a little while ago.
Many posts refer to refill bags, refill stations and compostable packaging.
I would like to agree with them here. The need for more environmentally friendly and economical packaging is becoming ever greater. This should be met (by Migros;)).
Perhaps the plastic bags for the fruit and vegetable assortment could be replaced by the chargeable bags and suggestions for taking along jute bags or baskets.
It would probably not be feasible to take your own packaging, such as tin cans or Tupperware, to the meat and cheese counters for hygiene reasons, would it?
