I HATE buying trash bags. I can never manage to get them free and yet I HAVE to have them.
I also do NOT buy cheap ones- since my garbage has to be walked through my living room to get to the garbage can it is an item I don’t skimp on.
So I use Hefty Trash Bags in my house. (I am sure there are other ones that work but Hefty goes on sale so they win.)
Right now on Amazon you can grab Hefty EZ Flaps Tall, 13 Gallon Kitchen Bags, 80 Count Boxes (Pack of 6)  for $42.58 when you use Subscribe and Save (on the right hand side of the screen).
That is only $.09 a bag- which is a pretty good price. They get delivered to your front door and since you will have 480 trash bags hopefully you won’t need any for a while!
Remember this is Amazon- the price can change at any moment!
Thanks Passion for Savings !
