There probably isn't a dedicated Qatar website and your searches turn up only those closest (UAE) or that cover the world (global) in the hope one will have the info you need/want.

Ask here if anyone knows where you can find these items/brands - narrow your search here and other Qatar websites (expatwoman for example).

Is it annoying that the marketplace here is not considered big enough to set up a webpage dedicated to it? Sure.  Is it surprising? Not IMHO
