Hi,
Yes, we have a 30-days money-back guarantee.
HikaMarket 1.0.0 does not have yet all features that we wanted to implement but HikaMarket 1.1.0 would be release in a few days and would contains some new features.
Each time a new feature is finished and validate, we update the change log in order to "announce" it.
