Use current prices at Adorama and B&H as your benchmark. Prices on the 5D have been fluctuating a lot recently.
Be aware that many people think that an upgrade to the 5D is very likely to announced by the end of this month (see http://www.bobatkins.com/photography/digital/canon_eos_5d_mkII_4D_6D.html). It will certainly be more expensive and some people may think that a 5D at a lower price will still be an excellent choice, but be aware of the facts (or at least the rumors!).
Unless he knows all the facts about the 5D, the possibility of a new model next month and still knows that he really wants the 5D, I wouldn't surprise him with one next week.
BTW I bought a 5D a couple of months ago while Canon were offering a significant ($300) rebate on it, despite my belief that a new camera would likely appear in the fall. The 5D at the right price can be an excellent choice even now, but as the prices on it rise it gets less attractive. I suspect the new model will likely retail at around $3000.
