My BF and I have been together for almost 8 months.  He said that he has already purchased my V Day gift, nixing my idea to keep it informal and simple since he is difficult to shop for.  So now I am in a bind.  I want to spend $50 or less.  He is a young (22 y.o.) professional in the commercial real estate business, he already has almost everything you could imagine, and the things that I know he wants are more expensive than I can afford right now.  Please help me. 

V day was a while ago so I guess this wont apply for this time. =<

My girlfriend and I make stuff for eachother. (both 18) It's not as hard as you think and I cant tell you how much I enjoy getting gifts she's made for me.

You have plenty to choose from:

Write a poem and frame it

Draw/paint a picture capturing your feelings, or a memory you have with your boyfriend

Put together a photoalbum and bind it in leather

Cook a romantic meal for the two of you

Use your imagineation.
