Getting value from giveaways with multiple copies

Hi. Sorry for maybe the usual question here but I haven't managed to find any similar one yet. So, the question is: when I create a giveaway and want to share for example 2 copies of a game valued at $20, do I receive double value to my account after the giveaway has ended? Like 40 dollars, instead of 20, because I shared 2 copies of the game. For me it seems logical but I don't know if it is true here, on Steamgifts. I know only that people would spend 20 points for a giveaway, no matter how many copies does it have. But is it the same way with account value, as explained earlier?
