PC Micro Store again takes 40% off its PCMS CAT6e cable orders of $4 or more via coupon code "CAT640OFF". With free shipping on most items, that's tied with our mention from two weeks ago and puts many cables at the lowest total price we could find. After the discount, and with pre-coupon prices tallying $4 or more, 5-foot cables cost $2.40, 7-foot cables cost $3, 10-foot cables cost $3.60, and 20-foot cables cost $4.80, among others. Coupon expires after 1,000 redemptions.
