No its not, some people still buy them even its temporary, did you think because you doesnt want to buy it then it became waste of space? Think about other people too dude, don't be selfish, and like what other dude said its your own fault for not actually read that it is temporary.

If you want to say its a waste of space, might as well said monthly card/medals is a waste of space also (since its not permanent either and not everyone buy it)
