Got our first paying customer

A month after launching premium memberships, we finally got our first premium member.
I received an email saying that they tried to purchase the premium membership but the checkout button wasn't working... The reason was that Stripe only works on https and they were on the http version. When I saw the email I immediately set up a redirect to make sure this doesn't happen again, but it made me wonder if we missed out on some other potential premium members until now...
