Amazon again offers the Seagate Expansion 3TB USB 3.0 External Hard Drive, model no. STAY3000102, for $139.99 with free shipping ($0.05/GB). That's tied with our mention from nine days ago as the best deal we've seen on this hard drive since last fall, when it was $29 less. (It's a current price low by $23.)

Note that it's currently listed as out of stock but still orderable at this price. No ETA is mentioned.
