Price check, please!

Alright folks, I need someone to help me out with this one.  So, I'm walking through the beer and wine section of a little market today to see if they had anything different than the grocery store and I see Sam Adams Octoberfest.  I was excited because I haven't seen Sam Adams at all since I've been here, and this one said it was one sale!  But upon further inspection it was far more expensive than I expected it to be: 2.15 EURO per bottle.  Most of the beer sold here is by the bottle, not in a six-pack.  If I were to buy 6 Octoberfests here it would run me 12.90 Euro, which is about $17.65 USD.  Am I the only person who thinks that's insanely expensive, even if it is an import here?  So your homework is to see how much a six-pack of Sam Adams Octoberfest is the next time you're in a grocery store and let me know! I'm curious to see what the difference is. because I knew alcohol was expensive here but I haven't taken the time to figure out just how much more it is.  Thanks!
