Amazo.com refund - Will Amazon give me a refund on a Toshiba HD DVD player...

...I purchased in January? I opened the player and have been using it. The website says it will give partial refunds after 30 days, but I have no idea what partial would mean. Does anyone have any experiencing with refunds with Amazon after 30 days. I'm also looking for any ideas for getting a refund on this and using the money to get a blu ray player.

I had something to return their past the 30 days and they said that they take 20% off as a restocking fee! I thought that was ridiculous so sold it on Ebay instead. The % might vary though depending on the product, so you should probably call them. Also, you need all of the packaging and everything.
