What surprise can I give my girlfriend on her birthday?

Plan something big for her. Travel all the way from your place to her; buy a Birthday cake and some candles and take them with you. Call her at midnight and surprise her by showing up yourself in front of her. This will really make her happy for sure.

How much should I spend on my girlfriends birthday?

If you're hoping for an average figure, most people spend $100 on their partner. But if they've really made the nice list this year, $150 to $300 is a good ballpark number if you can swing it.
