As one of its daily deals, A4C offers the refurbished 4th-generation Apple iPod touch 8GB MP3 Player in White, model no. MD057LL/A, for $54.95 with free shipping. That's tied with our July refurb mention as the lowest total price we've seen for it in any condition. (It's also the best deal we could find for a refurb today by $11.) It features a 3.5" 960x640 Retina display, front- and rear-facing cameras, and iOS 5. Deal ends today.
A 90-day A4C warranty applies.
