Do you want a used copy or new one? Go hastings has the game for $40.76 shipped. Half.com has "Like New" copy of Heavy Rain for $38.33 shipped. Half.com "New" copy of Heavy Rain is $42.49 shipped. On Amazon Marketplace, it is $38.98 used - very good from GoHastings. It is actually cheaper buying from Amazon Marketplace for them rather than there website.
I hope this gives you a little help in seeing a good price. $35 and lower is still a little off.
