Best Buy via eBay offers Insignia 5-Port USB Hub for PlayStation 4 for $7.99. Opt for in-store pickup to dodge the $3.99 shipping charge. That's $2 off and the lowest price we could find. It's designed to fit directly into the front of the PS4.

Update: It's no longer available for in-store pickup via eBay; however, Best Buy offers it for $7.99 with in-store pickup.
