Wow. 50% makes there drives close to actual prices.. since they (Office Depot) normally charge an ass ton more for their hardware.
They don't mark up 50% over other places... not for drives. $60 for a 320 is a great deal.
I have to point out that they would have to mark up the prices 100 percent for a 50 percent discount to return the drives to normal price. If they marked up the prices 50% and then decreased them 50%, your end price would be 75% of the original price.
