steripens are also small, and REI has a no chase policy...
Unfortunately they are usually locked up in a case, but just put on you nice clothes (or some of theirs...) and ask for one, then run for the door.
I saw some kids steal a kayak full of gear from REI one time. Probably 5k worth of shit. Great.
Can also do the return scam there, go garage sailing, or look at second hand shops. doesnt matter if its 10 years old, they take everything back.
They also have "used gear sales" once a year, and most of the things are returns, not acually used.
