Can't turn down the volume of my Sansa Clip Zip

Kerrigan, you should go back to the seller and ask for a refund or replacement, as your player does not meet the terms of a “new” unit, under Ebay’s rules. If the seller won’t help you, you can file a grievance with eBay and get your return/refund that way–this must be done within 45 days of shipment of the item to you. (Be careul about that deadline–eBay is strict with it.) Alternatively, you could seek a warranty replacement from SanDisk, but if it were me, I’d keep that as a second-best solution: I’m not sure how SanDisk Customer Service would respond to an eBay purchase of the item (as vs. a true store purchase, unless you purchased from a store selling on eBay); and even if SanDisk were to provide a replacement player to you, SanDisk could replace your player with a reburb. unit with a limited warranty–personally, I’d prefer a new one.
