You should be fine below a certain dollar amount BUT you have to go onto the sight on the back of the card and put in your zip code to associate it with the card and you can make online purchases. There is no worry of straw purchases or anything of the sort because it goes to the FFL to be transfered. It does work to buy gift cards on here for sure.

What you can do is buy a Buds gift card with it, then use the gift card to buy the firearm. Gift card codes are given online at time of purchase. So you can do it all in minutes.

This is an interesting question. To avoid straw purchases, it may only be allowed for non-firearm purchases. I would contact Buds directly at 1-859-368-0371
