Stinko absinthe
If you like absinthe or are looking to try it, Stinko is a great place to start. For 50 euro (31 euro shipping) you can get a bottle of their Grüne Fee (green fairy). I received it in under three weeks.
The Skinko site is nice because it lists thujon AND alcohol content. I prefer a lower alcohol / higher thujon mix. It also lists products without anise. There's one mix in particular that I've been anxious to get my hands on, it's called "King of spirits GOLD". Stinko doesn’t sell the gold brand and it usually goes for about $199 + shipping. Its way out of my budget but absinthe-order.com seems to sell a house brand for slightly less.
There's a group of people at burning man who make their own. You can buy the ingredients from them online.
