Thank you for the quick responses!
Concerning drop shipping, not too keen unless it is the only good option. For instance if I where to sell products from the USA in the USA. But must still do some research as to if this is possible or not. The payments are usually the problem here as you need a bank account in the USA.
I would like to buy stock rather, and ship this out to the customer when purchased. I will definitely make use of the Research Lab, thank you for that.
I will not give up and I am determined to make this work! I will continue to look for that/those "niche" item/s to sell in New Zealand, and hopefully abroad.
Thank you for the help, it is really appreciated.
