I enjoyed reading this manuscript. It is clear that the reviewers also liked it, however, reviewer #1 asked that uncertainties are considered. The authors have indicated in their responses that they have done so in a revised version of the manuscript, which I am looking forward to read. The manuscript has been given major revisions to allow reviewer #1 to comment (otherwise it would have been minor).

Dear authors, thank you for the revised manuscript. I agree with the reviewer that you need to point out the limitation on price estimation more clearly and therefore ask you to expand your conclusions and discussions with substantial paragraphs reflecting the reviewers comments.

Thank you for your revised version. You have extended the manuscript and addressed all reviewer comments sufficiently.
