My grocery store has switched to a bigger, deeper, stronger plastic bag to hold more groceries and use less plastic bags. I wouldn't use the canvas bags. Why not just bring an extra large duffle bag instead? It'd be better than carrying around 20 canvas bags to carry home hundreds of dollars of groceries. But, if you did that, would they think you were shoplifting? Paper bags are cool. Some stores have handles on their paper bags but it's been years since I've seen that. Can those bags really handle a gallon of milk and a gallon of juice?
Good thought on the TV's. Why won't they work? COX says they will if you have their service. It's just the over-the-air people who would need to get a converter and then they will be fine. I don't think there will be that many TV's.
