It has come to my attention that lithium batteries, even coin-cells, are considered hazardous materials when sent through the US Mail. There is a risk of them rupturing when traveling by air to their destination, as most cargo holds are insufficiently pressurized and/or temperature-controlled to prevent this. Since the additional expense of using only a ground carrier would not justify the inclusion of said batteries, I have decided to allow customers to purchase said batteries in their own locations and subtract any cost of batteries from the prices of all items, whether in stock or on commission. I apologize in advance for any inconvenience that this may cause.
