I've been using Social Snap for a while -- ever since the big hack job that Social Warfare experienced. Love the plugin; it seems lightweight and keeps all my social proof from my pre-https days. But it normally costs $39 a year at the level I use. Lifetime for that same $39. No brainer!

It was easy to turn off the auto-renew on my old subscription and then just change the API Key to the new one I was given. Didn't have to reinstall the plugin or reconfigure.
