That shows as $15.99 for me, but still the best price at NewEgg for a 4-port USB 3.x card (with
or without an NEC chipset). If you need something with an internal USB 3.x header to connect to a computer case's front panel USB ports, there's:
4 Port PCIE PCI-e to USB 3.0 (2 x Type A+ 20 Pin Internal) Expansion Card Hub Controller PCI Express Card Adapter w/ SATA Power
2 ports on the back, a 2-port internal header to connect to USB front panel, SATA power connector, the same NEC UPD720201 chip as your deal, $18.88 + tax with free shipping.
