what's the best birthday present for your online friend?

I know her for 6 months and her birthday will be next month. She is really amazing and I thought of surprising her in her birthday. But I've been thinking of a lot of ways but then I'm also broke to buy something like gift cards or anything. The gift shall not be costly but the most important thing that it shows love and caring and that's what I need. So what do you guys suggest? How do I make her amazingly surprised?
