Hello, im just curious if there is any SSL comparison site where is updated data on where to buy cheapest SSL certifficate?

What to search on google?

I searched "$4 SSL" and this comes out:
http://www.ssls.com/comodo-ssl-certificates/positivessl.html $5/year cerifficate
https://cheapsslsecurity.com/comodo/positivessl.html $5/year certifficate

If there is any $2.5 action price i would not much delay..
There are free SSLs but its only for personal use and i need it on business domain // UPDATE: letsencrypt is free business use SSL!!
