Thanks to Jen D. for the Reusable Bags site, via Spouseview. Plenty of options for reusable grocery bags, lunch bags, totes, and bottles. I was happy to find sports tops for our SIGG bottles.
What really caught my eye was this item, the Basura bag for $24, made in the Philippines from used drink pouches. I have one, bought from the Philippines, though I think I paid about $5 for mine, and it makes a handy swim bag for goggles and soggy towels.
