I'm interested in purchasing a quantity of elemental arsenic, specifically 100 grams. Could you please provide me with your best pricing for this product? Additionally, I would like to know about the shipping options available for delivery to Pennsylvania, USA. It would be helpful if you could outline any relevant shipping costs and estimated delivery times. Furthermore, if there are any minimum order requirements or bulk pricing options, please include that information as well. I'm looking to make a decision soon, so a prompt response would be greatly appreciated. Thank you!
