Quick way to test a scales accuracy.

[dank ass nugs]

yeah, but if you buy a sack you should always weigh out of bag, or if u dont want residue on ur scale, just rip off the zip part of the bag because it ways alot.... my freind bought an ounce, and he weiged it in bag, and the bag was a big hefty with a easy zip lock, and the bag weighed 3.6.... and the ounce weighed out to 28.4 in bag

Or else have 2 identical bags 1 to put the weed in for and then you wiegh the other to check wieght of the bags then minus that from the bag with the weed. Another way is to put the bag on the scale then zero out the scale and then put the weed in. And that dollar thing is a really good idea unless you have a fucked up dollar.
