My favorite place to find Converse is Marshalls, where you can pick them up for $20. I bought all the black/colored tongue ones there. I've found quite a few online though when they're onsale however. Famous Footwear is good because of their buy 1, 2nd half off. Of course zappos.com has the fastest shipping and are great, but it's hard to find Chucks on sale there.
Why do I have so many Converse? Well.. it doesn't help when your wife is a shoe-aholic (70+)!
