Welovefine has updated their stock with even more shirts and sweaters, along with the addition of full on posters. I'm actually impressed at their speed now days. It has only been a few days since the last episode, and already the Big Lebowski has raided their selection.
As for the sweater line, a few of the more popular ones have popped up, including Sweetie Belle's "Dumb Fabric".
Note: I don't know if that code thingy on the side bar works on the posters, but you can give it a shot if you want one!
