I don't know if things work the same in the US, but here (New Zealand) the SnC can be bought from some computer equipment suppliers. I got my SDX almost a year ago when a computer supplier had a deal, plus which Brother was running a cashback offer, so all in all it was the sweetest deal I could get here. I shared it with one of my friends, who called me rude names (on behalf of her bank account) and then rushed to place her own order
Have you tried searching for it on a price comparison site and see which suppliers come up?
