As one of its daily deals, A4C offers the refurbished Sony Walkman 4GB W Series MP3 Player in Black or Blue for $39.95 with free shipping. That's tied with last month's refurb mention as the best price we've seen. (It's also $25 under the lowest total price we could find for a new unit.) It features playlist compatibility, 4GB of storage space, and water resistance up to six feet. A USB charging cable and cradle are included. Deal ends today.
A 90-day A4C warranty applies.
