Orico Technology via Amazon offers the Orico Portable Mini 4-Port USB 3.0 Hub in Black, model no. W5PH4-U3-Black, for $9.99. Coupon code "52LIUXIN" cuts it to $6.49. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to bag free shipping; otherwise, shipping adds $8.22.) That's the lowest total price we could find by $7, although last month we saw it for a buck less. It features an 8" USB 3.0 cable and data transfer speeds of up to 5Gbps.
