expired Nitecore Tube Keychain Flashlight - $4.99 USD ($6.63 AUD) Shipped @ Banggood
Long time lurker, first time poster, so please feel free to correct any mistakes :)
This seems to be a good price for the well-renowned Nitecore Tube keychain light.
No coupon required.
This deal will likely expire at the end of Banggood's 10th anniversary sale (so around noon tomorrow).
http://flashlight.nitecore.com/product/tube for specs.
I have one of these and it is extraordinarily bright for its size and price.
EDIT: Green seems to be the only colour currently in stock, others will be shipped out after the 15th (restock).
