Hefty Extra Strong Trash Cinch Sack Bags 30 gal 1.1 ml thickness (6 boxes of 55 bags) 330 bags total for $50 shipped plus tax ($8.33 per box after discount and promo code)

Staples has these garbage bags for $13.99 - $4.00 instant discount but if you buy 6 you can apply code 63643 which stacks with the instant discount (final price at checkout). So you end up at $8.33 per box of 55.

For comparison lowes sells the 33 gallon 1.1 ml (same thickness) Hefty extra strong box of 33 bags for $12. Granted the staples ones are 30 gallon size but you get 22 more bags per box. Amazon is over $13 per box of 55 plus extra shipping cost. Its a few years worth trash bags but takes up less space than the 8 12 packs of brawny paper towels I bought a year ago with 36 more rolls to use.

The price per single box is a nice deal but with buying six its a great price. This was posted earlier for single box and didn't get much any fanfare so I am posting it again with the six deal price.
