I think you're giving us to little information. What kind of card magic? Close-up? (Stand up or table?) Manipulation?.. Ye, you get the deal.
I'm not into coin magic, so I can't help you with that part, but I do a lot of card magic. But first of I wanna recommend 2 tricks that is neither of those two categories, one of them you've already mentioned.
DRESSCODE and Smoke. I don't have any of them yet, but I'm gonna buy them after all the good things I have heard about them. I usually don't use gimmicks, but I think these tricks are worth it.
Anyways, the Smoke gimmick is a very simple one and it's supposed to last for a really long time. If you haven't seen the trailer (You probably have) you should watch it. I have been talking to a lot of magicians about it and everyone says it's worth every penny.
DRESSCODE should also be one of those awesome tricks. I have been talking to Calen Morelli about it, and it takes maybe 5 dollars to make each gimmick (Calen, if you see this and I am wrong, please correct me. But I think that's what you said.), and the gimmick is supposed to last for about 3 months, which is very long since it's so cheap to make. Caseyrudd said that he was playing football while wearing it and it worked perfectly fine.
I'm going to buy both of those tricks.
When it comes to card magic, it really depends on what you're into. Since you have been into magic for 7 years, I guess you have Erdnase, but maybe the Indestructible Erdnase would be a good Christmas gift? Just an idea.
Are you only into magic or into flourishing also? If you don't already have the Trilogy I would recommend it. It's great.
If you're not into flourishing and want to start, I would suggest something like Genesis V1.
Another great tip would be to get the Daniel Garcia Projects. If I'm not wrong it includes all sorts of magic, so that could be a way of getting into more types of magic than just cards. And then of course you could just get playing cards. I bought a brick of Smoke and Mirrors V5 with my parents Christmas money...
Anyways, that's what I can come up with right now.
