I absolutely support this and would be willing to go further. Too many damn plastic bags, and too many people don't recycle them. Before I started using the self-checkouts in Giant Eagle, Wal-Mart, et. al., I would actually ask my cashier
not to use one plastic bag per 1-2 items - like, put as much in one as you possibly can. So then they would double bag them, which defeated the purpose. I started using self checkout.
Aldi does this the right way - it's like .25 for a paper bag, and I don't think they have plastic bags. I always take a box or a shopping bag in with me.
