JemJem offers the refurbished Apple iPad 2 16GB WiFi + 3G Tablet for Verizon in Black, model no. MC755LL/A, for $139 plus $1.99 for shipping. That's the lowest total price we could find for a refurb by $11, although we saw a refurb for $4 less last month.
A 30-day JemJem warranty applies. Note that it comes with a non-OEM charger and may have scratches, dents, engraving, or removed engraving.
