What the topic says. This way we can share our pointless and regretable purchases 
I just bought a monster ipod audio cable (overpriced, whoo!) and had to buy a new surge protector (again, went with a monster cause I'm stupid).
So now I can listen to my iPod's music on my stereo in my living room, which is super close to my office with my computer and iTunes (both in the same room, I live in a smaller downtown apartment).
Total cost with tax: $102.something CDN
