Ink Circles is still open, shipping orders placed through the site and orders to your favorite shops and distributors. That said, shipping times for printed charts seem to be taking a little longer than normal, particularly those headed out of the US. Fortunately you probably have something else to work on while you wait. ;-)
Three new charts were released for May 2020 and are now available through stores everywhere. I've also been adding Digital Delivery options for many older charts, including splitting up a few larger charts. To see the full list of PDF charts, look under Digital Delivery in the Catalog menu.
