Actually the deal is dependent on how much ram you want and it what style. Do you want 1gb, 2gb, 4gb? Do you want 2x1gb, 2x2gb, 2x4gb? What kind of a discount are you looking for? $5 off? Want to spend $100? Want to spend $80? Just go to newegg and find what you want in your price range. Doesn't seem that hard?
Keep an eye on otherworldcomputing.com. Now and then they have great deals on RAM that's been pulled from other systems, but you have to act fast because they're usually in limited quantities and go pretty quick. I picked up 2*1GB a couple of days ago for $18 including shipping, which I figure will hold me over nicely till I'm ready to move to 8 or 12 GB.
