It seems that the good people of Dufvenkrooks didn't really expect such a huge amount of visitors on their page wanting to get a free bottle of glögg! During November (next on the 17th and 24th) they'll give out 50 coupons (value 30kr) for which you can get a free "Lättvinglögg". The giveaway today pretty much broke down their website and it took quite a while for them to get it fixed. I hope the email will arrive anyway despite all the web-mess!
You can try it again here next Thursday at 11am, hopefully they'll be prepared next time!
