Rather than fit all the merchants in the sidebar (or, rather every sidebar pageview) .. I'm thinking of doing this - http://hartmarket.com/
... in the center column on the store front.
Is there a way to get padding before/after top/bottom of each merchant logo so it looks more like a bunch of logos than one huge box image? In my functions.php I've just set the images to w100/h22 and just want to get a nice spread inside my blockquote there.
