How do I find a cheap power cord for my Toshiba Satellite?

The power supply for my Toshiba Satellite laptop died on me a few weeks ago. I went to several electronics stores looking for a replacement. They wanted $80.00! As did the Toshiba website. I then went to Ebay. I typed in the A215-S7425 System Unit number from the square gray sticker on the bottom of my laptop. I was able to pay $10.71 for a power supply! So far, it's been about two weeks and it's working well. If you want to try this route Search Ebay . Just find the System Unit number on the bottom of your laptop and enter it in the search box.
