BudsGunShop.com - Use a debit card that isn't in my name?

No. Gf bought me a gun for Xmas, has to ship under the same name as registered owner (at least in CA), Buds wouldn't release it.

To be honest, the mossberg that I got was purchased with a credit card owned by my wife. Everything was good. No worries. Your FFL will only likely take cash. Depending on their transfer policy expect to pay between 10-40 dollars. Cash usually

As long as your FFL knows you, or your girlfriend is there with you at transfer, its perfectly fine. I've done it 5 times. Only the paperwork at the FFA is important. I've used my wife's online, then transfered it to me when it arrived with my card. Enjoy!

I would recommend using the card to purchase a gift card for the amount of the purchase. I am not a lawyer and this is not legal advise. I have asked the ATF this question when I was working for a FFL. When you buy online as a gift you would have to have the persons' who's name is on the order do the ATF paperwork then transfer it to the person getting it as a gift. If you use her card to purchase a gift card, you can then use you own info as the buyer online and do the ATF 4473 when it gets to your FFL.
