honestly, if he did reply and explained that his supplier set the price high or the mobo sold over there is that price, would you be satisfied with his explanation?

...coz if u're not, u shouldn't bother asking for an explanation, coz i can expect that's what he'll tell u.

if u're still desperate for an answer, just shoot him a PM and include a tracker on it to make sure he reads it. if he doesn't reply on MSN, doesn't mean he's ignoring u. maybe he really is AFK.
