10 Wood, Hawaiian-Themed KeyChains for $1. If you make it to Honolulu, Hawaii (on Oahu), there is "The Swap Meet" that surrounds the entire Aloha Stadium every Wednesday and Saturday. We must have purchased $20 worth when we were there in 2010 and we're going back in 2012, I'll likely ship back boxes of them. There were surfboards, Honu (Turtle) and flower key-chains made of wood and of decent quality.
We also look for deals on USB portable drives and can usually pick them up for a buck or two when they are clearing inventory to make way for larger USB storage devices.
