RadioShack has a 12 hour 50% off flash sale today on a weird assortment of items, but it does include CR 123 A batteries at a very good price. Also lightning cables, a power brick, 3 different soldering irons, and a couple of other things. Oh, and a retro design cassette player, one of those ones you carry around by the handle, but that does have USB in for recording. Like I said, a weird assortment.
The RadioShack name is now owned by different companies in different countries.
In the US, the name and all the remaining assets were sold in late 2020 to the same company that previously bought Pier One, which now operates only online, so the expectation is that RadioShack in the US will probably do the same thing, although time will tell.
