What's a perfect gift

everytime I buy my girlfriend something she eventually returns it...im not offended but are their any gifts for women that she's guarenteed to like. I think gift cards are impersonal

did you try getting her jewelry? Find out her ring size and get her a nice valentines day ring.

I myself end up getting my mother gift cards because she loves them. as for jewelry, some women might like it...if you think your woman is kinda picky then jewelry is not the way to go, there's a lot of choices, colors, metals, cuts, etc. where you can mess up and get the wrong thing. See what she is getting when she is returning her unwanted items and go for something in that area.

Buy her something nice. Like a box of chocolates and roses with a little stuffed animal would be nice. Or, if you know a perfume she really loves is also a good gift.
