The charge would be fine if the bags were sufficiently strong not to
deteriorate before you get your purchases home. I have two "bags for
life" which normally cope with the weekly shop and get reused each week
as they are up to the task. There is no point in keeping a normal
supermarket or B&Q carrier bag because they are flimsy and drop to bits
and cannot be reused. A charge for something useless would be wrong IMO.

They're not useless. They get your shopping home. And IME they can be
reused a few times.
