Online Group Buy order form. This initial Group Buy will be limited to the following items:
cobalt carbonate, copper carbonate, tin oxide, and cones (you’ll be able to specify large or small size etc., and which temperature type).
OPA Members will be prompted to select the quantities they want (with chemicals bagged in 1lb minimum amounts), and then to pay by credit card. There will also be an area for you to write in what you want to see in future Group Buys.
* Prices listed for each product are adjusted to include the cost for shipping and processing fees. So the prices that you see reflect the exact amount you will need to pay.
* You must be a 2017 OPA member to participate in the group buy.
