Help with Christmas gifts please.?

I am thinking about what to get my family for Christmas. I have 2 older sisters, two younger brothers, my mom and dad, and an uncle who i am buying for.

Saying that, nothing can be overly expensive.

I actually already know what I am going to get my mom, so don’t worry about that.

My dad. He is addicted to eBay, like all things Mac, likes old copies of Popular Science and Mechanics. He isn’t into sports or anything. I was thinking maybe a gift card to the Apple store? Or a gift card to Barnes and Noble maybe.

My oldest sister is 21. I’m not really sure what I should get her.

My next sister is 18. She is in college for veterinary technician. She likes animals, and she also likes jewelery and designer things. I was thinking maybe some jewelery because her and her boyfriend just broke up, and almost all of her jewelery was from him.

My brother is 12. I was thinking of combining his and my other brother, who is 9′s gifts. They like video games. We have a Wii. I was thinking either a couple of cheap games, or something.

My uncle is into Harley Davidson. Anything with that on it would be good.

My budget is about $20 each. A little more maybe. I am open to anything.

Links would be nice, but if you just have ideas that’s fine also. : ) Thanks in advance.
