I think that you should purchase some thing with that $30. She needs to be able to enjoy the gift she gave...so, find a nice box of .454 Casull ammo (Winchester 260 grain Partition Gold, for instance) and plunk the certificate down.

Now, you are all set as you find that perfect FA to match her gift.
