Ethernet cables, CAT6, RJ45, 15 foot, 5 pack, Amazon Basics, black only for $6.88 (or $5.85 with coupon) at Amazon

Amazon Basics CAT6 ethernet patch cables, 5 pack of 15 foot, black only, $6.88 with free Prime shipping.
This deal only works on the black color and the 15 foot length. Cables are very good quality with 84% 5 star ratings.
When I bought mine there was also an Amazon Basics "loyalty" coupon code for 15% off one item shown under the price, so mine was $5.85 for one pack. But YMMV on that part.
