Price: 0.005 ETH per cell ($1.95 as of 2020-08-12) and free shipping within the continental US.

Someone suggested it, so I've decided to sell these for Ether as it'll save 5-20% on eBay/PayPal/credit card fees. I'll ship anywhere in the continental USA or Canada (add 0.09 ETH) via USPS / FedEx Ground.
