Does modmore.com use Commerce, too?
Not yet, but we're working on it! Given the many years of legacy and bespoke logic we've amassed in our custom billing engine since 2013, this has proven more work to rebuild than expected. Getting our own site to use Commerce is also generally a lower priority then helping our users, so internal deadlines have moved pretty often.
When we've launched, we'll be sharing information about some of the challenges we encountered in the process, and improvements that made it into Commerce as a result.
