DirecTV Now’s limited-time introductory $35-per-month subscription deal is going away early next month. AT&T’s website confirms that the “Go Big” package of over 100 channels will switch to its normal $60 monthly cost starting January 9th.

If you’re at all interested in the streaming TV service, you should sign up before that date — otherwise you’ll miss out on the promotional price. If you do start a DirecTV Now subscription by the 9th, you’ll be able to continue paying that $35 each month without being switched to the more expensive subscription plan. Once the limited offer ends, there will still be a $35 plan, but with significantly fewer channels:

AT&T has said that anyone who subscribes to the $35 promotion will be locked in at that price. But for how long? That part’s unclear. The DirecTV Now website plainly states that this “offer rate may increase,” and AT&T executives have already admitted that the service’s pricing structure is likely to rise in the future to account for the costs of signing deals with cable channels. Oh, and those channels might go away with little or no notice — something PlayStation Vue customers are now familiar with. Yeah, some people might just be better off sticking with traditional cable.

But we’ve found DirecTV Now, in its currently early incarnation, to be a decent bargain for the $35 / 100 channels price. I’d seriously hesitate to pay more than that at this stage, as I’ve been getting emails from some customers upset over bugs, streaming issues, and other viewing problems in the weeks since the service publicly launched. If you want to see how things fare for you, you can sign up for an entire free month using this promo code over at Slickdeals. Normally the free trial is limited to one week, but this gets you more time and in on that temporary $35 pricing before it’s gone.
