I just have noticed that Cosaru.com email hasn’t been delivering the incoming email properly. I’m fixing the problem now and at the same time I have turned off email’s spam filtering system in order to make sure that I receive all email.
If you have emailed me in the past couple of days and not received my reply, please email me again to order@cosaru.com
I apologize for any inconvenience.
