All ecommerce sites should be secured with SSL, otherwise majority of potential customers may decide not to buy from store that is not SSL protected.
If you are hosted on CloudWays you can easely enable SSL certificate for your site. It’s absolutely free. Please see the video lessons where I explain how to enable SSL.
If you are hosted with other ISP, then you should contact them about SSL. Some of them may also provide it for free when other will require payment for example on anual basis.
