When is the best time to shop for a suit

Hey there, first post. Love the site. So I realize that don't pay retail is the montra here. So besides ebay which still scares the bejesus out of me to purchase a suit, what stores and what time of year is the best to shop for men's suits. Here's the trickier part. I'm a thin 36R. So my selection is painfully limited. I live in Los Angeles and always check the Rack when I go and have been to the big Macy's sale both at Bev. Center and warehouse sale in Santa Monica. I think I've seen two 36R's. As much as it's considered hipper to do the two button suit. I think that the three is more versatile. I like two button for the no tie look or hipster thin tie monochromatic thing, but I need this suit to be both hip and a bit more formal. The other problem is that I'd like to keep it at around $750. Any suggestions? Any reputable ebayers would be welcome. I've been trying to get caught up with those existing threads.

You couldn't resist could you? Oh the wit.

All good points (3pm, Mondays, when you don't really need one). I guess I needed to be more specific (my fault). I don't think my weight will be flexuating enough to make that much of a difference, especially in shoulder and chest, since those are the most important points, right?. Called the southcoast nordies rack and they have 1 suit 36r with flat front and vents (yikes). So I've been checking out the thickasthieves site. Looks interesting. Do you know if they have a walk in shop sort of thing. I like the mod look but don't want to lean that way to much. I'm sending an email off to them. Any members own a suit from them?
