This doesn't really appeal to my boss. He believes that as a medium-sized, reputable business, if a customer noticed that change in the URL, it would either a) deter them from continuing, or b) make us look smaller/less reputable than having our own SSL. I understand his point, but I'm not sure that many users will care. He uses Shopify for one of his side businesses already, so he is familiar with the platform and loves it, but just isn't sure the SSL issue is fitting for our business.
I guess I'm looking for some other peoples opinions on this issue. Sometimes I can convince them to make changes even if they don't like to, so I'd like to have some opinions and info from other people to back me up a bit. We have many more pros for making the switch than cons, with the cons only being the SSL.
