One Arizona Cox user writes in: "Over at the Cox site for Arizona they have put up a couple of new tiers of service and lowered the prices of the 12Mbps/1Mbps service to $50. Their 7Mbps/512kbps service has also been lowered to $30, so that should turn up the competition over at Qwest." Not to obliterate his excitement too much, but these are three-month promotional rates.

Qwest currently charges $20 for 256kbps/256kbps, while Cox now offers a "lite" 512kbps/256kbps tier for $10 for three months, after which it's $15/month. The 12Mbps tier mentioned above is $50 for three months, after which the price jumps $10 to $60/month.

Cox prices and speed (and sometimes even tier names) vary depending on local competition. As we've often discussed, in some markets these lite tiers aren't advertised -- instead, they're only offered to customers who threaten to cancel.
