SEO is doing great, should I try PPC too?

I have been doing great after the August updates. Many of our keywords are just ranking at the first or second position of the SERP's without any much effort and conversions are really good. As without investing much money we are getting pretty good amount of sales.

Now, I might be getting greedy here but I was just wondering that if we some small amount of money in PPC now, will it maximize or sales? Many of our customers are from mobile and use social networks much. So, I am also considering running fb sponsored ads.
