Any idea where to find a good deal on trash bags? I buy mine at Home Depot. They are 3 mil and 42 gallons. I believe 30 come to a box and they cost about $10. I have tried bags that are 1 and 2 mil and they do not work for us. I go to Home Depot once a month to buy trash bags. I know it would be cheaper to find a good price and buy a year's supply upfront.
