The scraper is green at 83.33%, this is lower than you can buy one for at a vendor, so green means bargain in this case and I'm selling at a loss to myself.
Grain is red at 130%, this is higher than I could get for selling it to a vendor, so I'm trying to make a profit on it.
Meat is green at 80%, this is the same price as I'd get for selling it to a vendor (80% of the items cost), so it's also technically a good price. I actually make a loss selling it for this price though after commission and listing fee's.
If I'm wrong, by all means correct me, I'm kinda new to the market side of things and only been trying my hand at it a couple weeks.
