Here are a couple more of plastic bag recycling bins that I found at local stores in my area.
Shown below is the Plastic bag recycling bin found at Lowe's.

This is the bin that I saw at a local ACME store.

ACME is part of the SUPERVALU, Inc. chain of stores. According to their website, they have more than 2,500 stores (Albertsons, bigg's, Bristol Farms, Cub Foods, Farm Fresh, Hornbacher's, Jewel-Osco, Save-a-Lot, Shaw's/Star Market, Shop 'N Save and Shoppers). You might find a plastic bag recycling bin on a store near you.
