Comodo Positive SSL for $9/Year offered by namecheap is really very much cheap in price, but there is one more SSL certificate vendor "CheapSSLSecurity" that offers comodo Positive SSL at only $5.99/Year and if you are purchasing it for 5 year then the price is most cheapest at $4.80.

For Wildcard SSL Certificate I've found that "CheapSSLSecurity" offers it at $72.95/Year and $58.36 for 5 Year.

I bet no one can beat CheapSSLSecurity's price.
