Sorry for the thread hijack, but I accumulated my vouchers and generated one for BTC 0.0196 (and have since accumulated BTC 0.0032 more). Since I'm not going to be using it, perhaps someone's interested in it here. PM if so.
As long as you are giving it away for free

Well, dailybitcoins' owner has stated before that "...you can generate redeemable voucher codes to sell or transfer funds from your advertiser's account." (
https://bitcointalk.org/index.php?topic=265401.msg3038202#msg3038202), so according to that, it's allowed to sell them if you wish.
That said though, sure. Even though that amount would pay for a lot of views, it certainly would be more helpful for someone else than me right now, so yeah.
