Well I don't know how much higher the expectations of a wife a re compared to a GF, but when I really like who I'm seeing, I get them something personalized, or something that they would never buy for themlselves.

E.g.: A scarf with her name embroidered on it.

Something she will constantly use and enjoy will give you the opportunity to remind her how thoughful you were/can be in strategic situations

P.S.: www.pajamagram.com , fits the agreed price range too :thumbsup
