Uh, WTF *can't remember that in the anime at all* No, she never does that in the manga. The most presents she's gotten were regular hoop earrings from the brothers, and that was just to apologize for stuff; she didn't ask for that and never uses her curves for anything.

And hell, even if you still dislike manga!Winry anyway for other reasons, you really should give the manga a huge chance. The plot and characters completely different to the anime version, and it's really complex and detailed for a shounen.
