After searching the web and comparing the different price rates, I just found a lowest wildcard SSL at $42/yr. at https://www.ssl2buy.com. I hope that you would not find cheaper than this wildcard SSL. As they did not charge any extra beyond the price and helped me to secure my number of sub domains. Even the backend technical support was good enough.
How much RAM do you need for gaming? However, I have 8GB RAM but the game hardly takes 4GB for functioning. One of my friends has 32 GB RAM but I think he is more paying for it. Is more than 8GB RAM needed for gaming?
You can purchase an SSL certificate individually and install it manually on your Heroku server. I bought my comodo certificate from ssl2buy.com only at $10, they provide free installation support.
There are main three types of SSL certificates: domain validation, business validation, and extended validation. If you are a small or medium business and would like to secure your website, then you can get domain validation certificate at very cheap rate. Compare to domain and business validation, you will find extended validation little pricey as it is ideal for e-commerce, financial, banking, social media, etc.
