Amazon offers Prime members the Hawking Technology 3-Port USB 2.0 Hub, model no. HU2P4, for $9.98 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping adds $8.12.) That's tied with our July mention and the lowest total price we could find by $8. As a USB hub, it's compatible with both Windows and Mac; however, with two Windows computers it works to transfer files directly via both PC's USB ports.
