if it happens dirk, please don't limit to 100 or so. I do Understand they can be out if stock and that its a pain to build then.
But once in a while you could say, "hey, right now i've decided for a new batch because i need a little extra pocket money".

or is it perhaps so that you make little or even no money out of them?
if thats the case i understand of course that you llimit them so low in count.
