A4C offers the refurbished Sony Walkman 4GB W Series MP3 Player in Blue, model no. NWZ-W273, for $44.95 with free shipping. That's $5 under last month's mention and $25 under the lowest total price we could find for a new unit today in any color. It's waterproof up to six feet and a USB charging cable and cradle are included.

A 90-day A4C warranty applies.
