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 a week ago and puts many cables at the lowest total price we could find. After the discount, 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.
