Simple.
You can get 100 feet of Axiom speaker wire for $100, or you can get 100 feet of Sound King 12 guage bulk speaker wire, which is rated as some of the best wire at that price, for $70 less. http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=100-155 shows it as being $37.50 for 100 feet, which makes it $62.50 less than the Axiom bulk wire for the same amount of wire.
That wire is really good, and a thick guage too. And if you'd like the fuzzy feeling of using better wire - instead of buying one pair of insanely priced wire, use all the extra wire you'll have left over in the 100 foot spool to bi-wire the speakers, since I doubt you'll use 50 feet of wire for two speakers.
