Didn't he say he's looking to NOT spend 2Gees?
Watch out for those "every girl loves" stuff. I always feel gypped when men go to Victorias secret- c'mon, you're not buying that for me, you're buying that for me to wear FOR YOU. And frankly I am too ticklish to enjoy a massage. Look around her place and pay attention to where she goes? Does she get her nails done every two weeks- pick up a gift certificate there. Does she burn yummy scented candles at home? Then go to Yankee candle. Do you know what kind of perfume she wears (if any)? Does she have a hobby (for me, keep the make up, I'd like a big Al's gift certificate)? Does she like to read? Note a couple books you've recently seen on her night stand and go talk to the people at barnes and noble- if you give them a couple authors/titles she's read they can steer you in the right direction.
Justahanna had a great point. If there is something she needs, those are often much better gifts than something romantic. You should know her well enough, is she a flowers and chocolate, designer bag, hair highlighted never leaves the house without make up type? or a mows her own lawn really wants crown molding type?
One of the best gifts I ever got were little gift certificates he printed up at home- things like "the bearer of this card is entitled to the washing of one weeks worth of dishes" and "one hot bath with candles and hot chai tea to be ready upon your return home from work" and other stuff- one trip to the market in the middle of the night for mint chocolate chip ice cream, one Football free fall Sunday, one trip to a family/friend event you know I dont want to attend- I could use them whenever I wanted and all I had to do was whip out the card- I LOVED those. It was one of the best gifts I ever got, and I used them all year! Another person actually copied a very romantic sonnet onto paper he had died with tea and burned the edges, rolled it up, tied it with a little red ribbon and put it inside an empty wine bottle (after he had removed the label).
