I need a affordable ssl cert to use on my site. Looking for no more than $100.00 but i would prefer under $50.00 if there is such a thing for my need.

I am going to be usijg it mainly for whmcs. I purchased one not know what i was looking for and it was self signed. To my surprise, every time i went on the secure sections i was getting the error on the browser stating it may not be secure.

I just need a decent one that when visitors go to the secure section, they dont get that message. I dont know what wording i should be looking for when researching. If you have a suggestion on a particular one, that would be very helpful.

Thank for the help
