Costco's Frozen Food Tote Bag is back - Red at $7
every year or two costco sells these excellent messenger style tote bags that are white plastic lined for freezer items and to contain spills. outside is a heavy canvas on the bottom is an extra layer and a strap the goes all around. similar bags sell on ebay and amazon for $15-$35, so $7+tax is a steal at your local Costco now. the blue version was being sold 2 years ago. the only improvement i made on this bag is to add a velcro strap to keep the 2 canvas handles tied together, otherwise i find they slip off your shoulder too easy. i often carry 30-40 pounds of produce and groceries in these bags, and even after 100 miles walking like that, they have not blown a seam or torn the lining. the costco logo is only on the on zipper pocket side. the other side is a simply plain canvas with the handle strap continuing down to the bottom. there is no internal pocket or keychain ring.
