Should I take SAT Subject Tests?

Hi there!

I will be applying to a 4-year college this spring as a transfer. Because I will have finished one semester of community college, I will have to send all my high school information.

My issue is that I took a GED, which means that besides my extracurricular activities, they will only have my ACT score and my semester grades from CC.
I was trying to create my fall budget, which includes college application costs, and was wondering if taking two SAT Subject Tests would make a difference in my application, or if they would just be extra costs.

Thanks
