The problem with bags is - let's call it the bachelor shopper. A modern man's clothes may have pockets, but he rarely wears any kind of handbag in which to hold the reusable shopping bag.

So it doesn't matter if they cost 1c, 10c or 1 eur - I am always buying new bags, have nowhere to put the bag when I am going outside. At least I also use them to throw away trash.
