When should i send my SAT scores to universities?

I just recieved my SAT scores and I have the option of sending a few score reports to colleges for free. I got a pretty good score, a 650 in critical reading, 700 in math, and 620 in writing; however, I plan on taking it again in October. Should I send the score report now or wait until after I take the SAT again and I start applying to universities?
