There really aren't that many copies of Milosz's poetic work at Cody's. Given that I'm really into his poetry right now, I expect the rest of the world to be in the same state of active engagement. A quick glance at the bookshelf at a local bookstore reveals otherwise.
Update: Lloyd wrote the following to me: "There might be more Milosz volumes at Black Oak Books, actually, in either/both the new and used sections. The folks at Black Oak always had a soft and warm spot for Milosz, who after all was practically the neighborhood poet laureate, living as he did just up the hill on Grizzly Peak Blvd (near my friend Jane's house, where I used to live; I'd occasionally see him when he'd be out walking).
