Can't be that much otherwise they wouldn't do it. They've run vouchers before, plenty of times. If it wasn't good for them as a business then they wouldn't do it.
Bluntly, I have no idea how Green Man Gaming is still in business. I realise the majority of the costs come from running the servers, but their prices, when combined with the DFS-esque regularity of their vouchers, regularly reach nonsensical lows. I think some publishers (mainly 2k here) are getting wise to their antics, however.
