Gentleman, have you heard of Etsy? No? Well, your wife has and you should know about it. I don't really know the best description to give you of Etsy, but the basic idea is that people make stuff and sell it. Think of it as the world's largest emporium. Every person has their own "Etsy store" where they can list multiple products that our wives will want to purchase. Some stuff is incredibly overpriced, some stuff is pure crap, and there is a lot of cool stuff.
It seems to me that most guys just stick to known safe areas as far as gift giving for the women. The fear is that you will give a gift that you thought would be good, and she will take it as an insult, or read something into it.
