I was busy and now my connection is so slow. Partiko and esteem do not load anything. I can only answer replies :( I wait for a better moment.

Here some supermarkets sell the plastic bags.
Aldi asks 3 cent
Lidl 99 cent!
The cloth ones are 99 cents too but you cannot use or buy them in every shop.

Strange thing is there are paper bags with a part of plastic in it and they are free!

I buy without bag and put it one by one at the cash desk. That wil keep them busy. 😁
