I echo the same as the last person.
Give them a call, you will get a far better deal, even if you half to hang up on them.
They will call you back wanting to sell you the system.
I had one guy calling me back for three days until he would give the deal I wanted, stick to your guns.
Also, memory upgrades are a stupid price from deal. Compare it to Kingstons or Crucial websites and you might find the memory cheaper there. I know I did.
