well, so far I am quite happy with them on the last few hot deals over the last year- first the "bargain bin" deals on Foxconn nforce4ultra 939 boards and 512mb cas2 patriot DDR for under $40ea, then the ASUS SLI mobo for under $50, and now this deal. All of those I placed for shipment, not pickup, and in all cases I got QTY of 4 to 5 received (eventually ), that is, all except the asus SLI deluxe deal, which seems everyone only got one of regardless of qty ordered, but one is better than none. Seems MC online will honor deals set to be shipped fairly well given time, but if you choose instore pickup you are more than likely going to end up getting the shaft.
And that just my 2cents (which, by the way- also bought two SLI motherboards )
