Our Kijiji is similar to Craigslist and people that shop on Kijiji are well not the most reliable and trusting.
I have a bunch of different key FOBs that I have accumulated over the years and sell them on Kijiji. I clean them up, install a new battery and make sure they work properly. This works out pretty good for me most of the time but there's always the one person that says " I want it, I need it, consider it sold, I'll pick it up today or tomorrow, can you hold it for me?" These are some of the FOBs that today I put back up for sale because they've been sitting there for at least a month. I just hang them on my shelf as I wait for the pick-up. So at least $300 worth of no shows.
