Richard, the owner, runs the business from home but is a MTN reseller as well as a reseller for the various electronics suppliers (Pinnacle etc.) and ran the business for a number of years before going online.
I recently bought a home theatre system from him with no real issues. My only word of advice would be to just give him a call and check availability of items if you are ordering any home entertainment equipment. The phones come direct from MTN so you can expect delivery from them as if you were ordering directly through MTN.
He's legit. I only have a few posts so my word is probably not golden, but take it from me - he's paid and is paying a lot of money for that site to break into the e-commerce market and works extremely hard at constantly improving his offerings. Considering the site took almost 2 months to build, it's very difficult to see how it could be a fly-by-night operation.
Those are some seriously good deals if you're in the market for a new phone.
