Ending today, TechRabbit via eBay offers the refurbished Apple iPad mini 16GB WiFi Tablet in Black for $167.99. Apply coupon code "P20FINDYOURTECH" and check out with PayPal to cut that to $134.39. With free shipping, that's $119 less than you'd pay for a new one today, although we saw a refurb in another color for $34 less a month ago.
Note: No warranty information is provided. Also, the above coupon can be used once per PayPal account within a single transaction.
