"Break even"? Who cares about the cost of reusable grocery bags.. really. We have 4 of them in our cupboard. Bought from Whole Foods. We use it everywhere we go

"Break even"? Who cares about the cost of reusable grocery bags.. really. We have 4 of them in our cupboard. Bought from Whole Foods. We use it everywhere we go. $40, maybe? Years ago..? That's not a real burden (to me), especially against environmental degradation, pollution, waste, etc. There's the suggestion that paper cups are more environmentally responsible than ceramic mugs, because of the carbon cost of making ceramics. You have to use hundreds of paper cups to achieve the same environmental impact of one ceramic mug. That's a consideration I'm personally curious about...
