Newegg Canada Shellshocker: 4GB MP3 Player $20 & Free Shipping
This is one of the deals of the day at Newegg Canada, for Sunday the 7th March 2010. They are offering the CENTON moVex Black 4GB MP3 Player for only $19.99, with free shipping too!
OK, so it's not a well-known brand, but it seems to be a decent player for less than $20. I think this kind of thing is perfect if you want to store a few albums to listen to while exercising - either while out walking, or running at the gym. If you drop weights on it, or drop it in a puddle, then $20 is not a big loss!
