I agree with the last two. I don't want to tell you it's absolutely fine to feel that way, or that different people have difference preferences. They acknowledged your birthday and did something special for you, giving you something no one else could have given you. If you would have rather received something materialistic, I think you should be ashamed. Talk to them, though. Tell them that you'd rather get something you can open than a special day with your loved ones.
