Shop setup
From Dreamwidth Notes
Edit $LJHOME/ext/local/etc/config-local.pl (copy it first from $LJHOME/etc/config-local.pl if it doesn't already exist) to uncomment the variable %SHOP. Note that it's multiple lines to uncomment, but don't accidentally uncomment the key => line which is a comment.
You will also need to install the CPAN module Business::CreditCard which is not checked for by checkconfig.pl and may not be installed.
