Western Digital Store offers its refurbished Western Digital 3TB MyBook USB 3.0 External Hard Drive in Black for $64.99. Coupon code "DNMB3TBSALE" drops that to $54.99. With free shipping, that's $5 under last month's refurb mention and the lowest price we've seen. (It's $34 under the best deal we could find for a new unit today.) It features data transfer rates up to 5Gbps. Deal ends April 20.

Note: A 6-month Western Digital warranty applies.
