Tacoma Mall has a Crocs kiosk in the middle of the mall. Might be worth the trip. Also, South Hill Mall has a Hallmark's store that sells Crocs, but I am thinking their selection is not as large as the kiosk at Tacoma Mall. The Hallmark's is called Coach House Gifts, it's right across from Auntie Anne's Pretzels. The Tacoma Mall Kiosk, if I remember correctly, is located along the corridor in the middle of the mall, between the plaza by Orange Julius and the plaza in front of Macy's.
Hope that helps! The kiosk has Jibbitz, but no Disney Jibbitz. I have to get my Disney Jibbitz at the South Hill Mall.
Thanks for the tip about the Tacoma Mall. Isn't there a Disney Store there too? I think that's where we went to buy T-shirts just before our trip to WDW a couple of years ago.
