It is ebay Singapore.  ebay.com.au tried to te;; sellers that buyers had complained about getting too many emails so they removed the ability to send bulk emails.  They don't even like sellers contacting buyers; you get an automatic 5 if you don't communicate with your buyer, put in a tracking number, and post within one business day (I think I've got that right).  Personally I don't return to sellers who can't even take the time to say thank you, but then I am an old fashioned bear;\
