Price is after $5 discount for autopay & paperless billing.. price for first 12 months only, afterwards prevailing rates apply... there are transactional fees, surcharges, and taxes yet to be applied to that price ... and worst of all, there is a $99 installation feeAND a $10/mo. equipment fee... suddenly your first 12 months at $35/mo is starting to look like $50+/ mo ....
.. but if your Cox internet service is cr@p.. it might be worth it.
You want to switch for the $35 per month, and I'll agree Cox is raising prices. All providers promote deals because it's common practice to lure people; however, it won't be $35 if you read the fine print.
Take, for example, the Carrier Cost Recovery Fee. What's in it? I don't know but it's not regulated because it's not a government-mandated tax or fee to you. Basically, it's the cost to a provider for doing business in a locality. [You want to do business in our locale? Pay our regulation fee. You made a million dollars last quarter, pay our locality tax.] It's whatever money a provider lost doing business and the provider will "recover" these losses from you: Carrier Cost Recovery Fee.
ATT will not lose money offering you a deal because ATT will recover the difference with official-sounding charges: "transactional...recovery...technician..." etc. I have to pay the Carrier Cost Recovery Fee but what will your rate be compared to mine? Will your rate be higher during your promotional period? Can ATT "recover" your promotional savings through this ambiguous charge? What's in it?
Bottom line: don't switch based on a common promotional lure. Switch to give ATT a tryout.
Promotional pricing is a scam because...as superbigwaff noted...providers will recoup money with hidden fees and inconsistent pricing the following year. I mean, if you can pay a lower rate, fine, but don't switch solely for a temporary deal.
However...it may be worth a shot to go with ATT for a more dependable service...if this was an issue with Cox..
