CoTD - $10 Day (with $10 shipping cap)
I recently purchased kids' headphones plus the magnetic fly screen from them at their last $10.
I was happy with the headphones and so's my little girl. (It has volume control so they can't blast their eardrums by accident).
The flyscreen is still in the bag, as I have been too slack to put it up, but looking at it.. I probably wouldn't as it looks a bit fiddly. Definitely looks better in the pictures.
