Not to plant.. I know how to do that... I sell bulk materials - topsoil, mulch, etc. I have a lot of customers wanting to purchase grass seed/straw as well.... My grass seed is in 50 # bags..... I normally just eyeball it, which I know is costing me money from eyeballing on the high side, because I am NOT going to give someone less than what they are paying for..... So, what are you guys using to weigh items like this?
