I have been using NZsale for 5 years now and my experience has not been that bad. I have bought some very nice stuff from them that gets very good remark and I have also bought some $#*!ty stuff from them which I did return and got refunded.
Yes, delivery takes long sometimes to receive orders but hey, I am not in a hurry and they eventually arrive anyway. Their prices seem to be reasonable too compare to other sites. Overall, I am satisfied with NZsale
