Its all economics willing buyer .. willing seller. If a .co.ke is expensive for your needs then get a .com at a fifth of the price and move on.  Those who feel that a .co.ke will give them value for their money at 2320 then take it up and bear the cost

PS: From the loud complaining here I can tell that a .co.ke has some value which the buyers don't want to pay for . Economics don't work like that. If people are really serious about the price being high ...  please go .com
