You should be able to get the discount by following the link I pasted and putting the unit in the cart by clicking buy now. If you need a longer, or shorter cable just click on links to bring you back out and then put your selection in a cart. I hope my link is active. If none of this works all I can suggest is refreshing the screen a bunch of times till you get the impact acoustics banner across the top to click on. You could also PM either Clint or Gene.
As for cable cost my gut is to tell you to take whatever is cheapest that will do the job well. For me it would be the $23 cable, it says it exceeds all requirements, and when a reputable merchant claims that then you can worry a little less. There are guys who do installs on this site for a living and I know that one Moderator even owns his own shop and I'd suggest that you PM them and ask their opinion. Seriously I'd PM either RLA, BMXTRIX, ANNUKI, Clint or Gene. I'd really you rather went with the last 2 because they own the site and I'm afraid I'd be stepping on toes to suggest otherwise. They will need to know type of equipment you have, and cable length needed. Those guys are all experts. There is also Buckeye, he is the member I always seem to get help from when I'm stuck and he knows his stuff too. Good luck, and by the way you were right, Monster is overpriced. It would do the job but no better than the cables listed or Radioshack gold for that matter but leave you walking with a limp the next day.
There are lots of other members that are experts in this stuff, I'm only posting a few, there are more that I could post but then I'd worry about leaving someone out. This is a perfunctory list.
