Dude. You already KNOW the "correct" answer to this...
Find out something she likes, then pretend to like it too. Then let her get it as "her present to you".
Life can be pretty simple sometimes. I didn't say perfect, I said simple...
Take 50$ of that and buy her an extra present, wife's are the unsung Heros of a marriage, thy have the babies, they get up at night with them, cook, wash the clothes, I could go on and on but you get my gist, when you see her face as she gets that extra present it"ll be better than any damn pipe or tobbaco you can buy. IMHO. The old cajun
I'd get a $40 bottle of booze, go to the B&M and blow the remainder on tobacco while drinking the bottle and spending the weekend there smoking my purchases. But that's just me.
If you don't take Bradley's advice, I would buy this pipe, http://www.smokingpipes.com/pipes/estate/italy/moreinfo.cfm?product_id=100302 and then spend the rest on tobacco.
