I don't know about online, but I have heard of a lot of outlets opening up at outlet malls. I found one recently at the outlet mall on Hilton Head, and I didn't even know that
Crocs had outlets. Then I posted about it and found that there a lot of them cropping up. I bought a pair of Disney Crocs for $9.99, and they were BOGO. There were many many pairs of Crocs, but sizes in certain styles were limited.
Here, I found a locator to see if there is one in your state.
