Ignore her. She does that to everyone who says free shipping. She doesn't like it when people get the 15 free credits when offering free shipping. She can't seem to remember that new sellers don't get those credits. You can ship them for free if you want. However, codes are best done through Listia for traceability (Listia agents can see you sent the code). And you can get your credits much more quickly, especially if you send out the code quickly. Just fanned you for putting up with her.
