Trying to get comfortable at buying lots of jewelry from folks on FB. I typically request a pic of what the seller has, but struggle when they ask me how much I would pay them by the pound. Do you offer a flat rate to folks for their lots or do you truly get out the scale and weigh the goods? How do you arrive at your per lb price? What's a good average per lb for an assortment of modern and vintage? I want to be fair to a seller but want to be savvy too.
