Good luck with the new venture, selling/buying online in South Africa is still too far away to be confident enough to make sufficient sales in this manner.

Much like you I learned, read/listened to copious amounts of content, then realized realistically sending goods overseas from where we live would be too expensive. People are skeptical, you cannot blame them.

Buying and warehousing via Amazon at one time, selling online using that method was enticing, again you have no control of your stock which left me doubting, really nice you have found a way through and once again good luck!
