Simply imagine a shop for clocks and watches and you see a large shop-window with maybe just 1 or 2 simple alarm-clocks in the window, and NOTHING else.
Go into the shop and ask for alarm-clocks - you will be lucky, as the shop has 1 or 2 for sale, and when you leave the shop is empty and has to wait for the next delivery tomorrow or maybe next month...
who knows...
