I toke a look at the marketplace, and this guy sells domains.
Claiming the original price is $11 to $12 on Namecheap, and his price is $5.
I asked him how'd he get those: "With Network Solution?".
He replied, yes. Most of the other costs are transaction costs.
Now he claims he gets them for the original price $11 to $12 on Namecheap.
