Fry's used to have things like this, but then they have been slowly not restocking anything even before the whole COVID thing hit.
Ham Radio Outlet has a store in Oakland I think, not sure if they are open for retail.
I did get a notice from Zip Scanners today that they had SDS100s in-stock and it's probably the last of their stock that they got earlier in July. A lot of the online scanner retailers (Bearcat Warehouse, Zip Scanners, Scanner Master) got their batches in waves (the last batch was in July) and once they are sold out, it will be another month or two for the scanners to be imported and the scanner retailers getting their batch.
