Two weeks back I got my first Mac (Mac Mini, low-end one for $499). Today, I see that the same exact one is $429! If I return the $499 one, I get hit with a $49.90 restock fee since it has been opened. If I then buy another same refurb, after tax, I'd be saving only about $25. Or, if I order and receive another one (but don't open it) can I return it on the original purchase? Or does Apple track the serial numbers for each order (model numbers are the same of course).
