Is there a cheaper option than this?

I need the absolute cheapest hard drive so I can repair this girl's computer. It needs to be 320gb 2.5" sata laptop hard drive. rpm doesn't matter. This is the cheapest option I've found so far, but I feel I can get a better deal somewhere.. anone have any suggestions?

I didnt really want to go used, but I opted for this one, that was allegedly pulled out of a brand new computer for an upgrade... so its used but its still brand new..

its showing 35 bucks for first one from a store and 30 bucks for the ebay one from a person

i would have sprung the extra 5 for the warranty

 

I probably should have but I'm just a dude fixing a wife's friend's computer.. there is no warranty expressed or implied in this situation. she already paid me so that extra five bucks is coming out of my pay. The hard drive I ordered is 7200rpm vs 5400 rpm, so there's that positive tradeoff too.. I'm only making 20 bucks and I'm updating the BIOS as well.

If it was mine I would be ordering a larger hard drive anyway.
