I was planning to post a similar question so instead of starting a whole new thread I thought I'd piggy back on your post. Hope you don't mind.
I have a further question:
Once you establish all your service provider's and ready to go with the eCommerce site, what is the most efficienct or sustaining way to ship orders to customers? I intend to open a online clothing store for a major client who might be needing to ship up to 1000 items per month to various locations across SA.
With regard to the other question about shipping items, I recommend Fastway couriers as their fees are very competitive, although they only deliver to certain areas.
