Knowing the cost per bag means you're more hesitant sealing cheap goods which add up to additional waste.
My 8x12 are half the price at about $0.10 each and 12x16 (closest I can find in Canada) is about $0.22.
My 6x10 are about $0.04.
Using historical values of $500USD ($661 CAD) minus $80 (or upwards of $200 for a "fancy" sucker) means $460-580 difference.
At $0.10/bag, you'll pay for the machine outright after about 5000 uses.
Unless quality has improved, your foodsaver probably won't last that long. I went through a half dozen machines in 10 years because they kept failing. I wasn't even using them that much due to cost of use.
Once you start sealing cheaper things you'd normally skip due to costs, those can add up to $500 pretty damn quick.
4x 8x12 your bags = $0.80.
4x 6x10 my bags = $0.16.
For $0.16 I can split a tub of $3 tub sour cream into portions. To spend $0.80 for the same project in a sucker sealer makes less sense. I'm spending 5% of the product cost. You'd be spending 25% of the product cost.
EDIT: Even rolls won't save you. Making a smaller bag means you're wasting 4 inches for sealing space on each end.
At $0.16-$0.19 per inch (on your site) making a smaller bag than a 6x10 isn't even practical cost wise.
The cheapest bag I see there is the 6x10 which for 1200 is $180 or $0.15 each. I just paid $37.50 for 1000 of the same size.
