I have 2 insulated ones I got at thrift store. I use one for meat one for all other cold items. I made several totes from the plastic grocery bags and they are very strong. I found heavy duty material at a yard sale and made 2 bags for my daughter. We love the reusable bags. I was the insulated and my crocheted bags (the grocery store plastic bags)with vinegar , all others in washer. They are holding up well.
