As just about every subscription service including Apple TV+ raises prices, "Star Trek" and NCIS franchise streamer Paramount+ is offering half off its subscription fees for new or returning users' first year.

Apple's price rise took Apple TV+ to $12.99 per month, with neither an annual option, nor a lower-cost ad-supported tier. Under the new special offer, Paramount will cost from $2.50 per month.

Get 1 year of Paramount+ for $30

Annually, it means Apple TV+ costs $155.88 — unless you have it via the Apple One Bundle — and Paramount+ costs $30. That's for the ad-supported version, but Paramount+ is also offering an ad-free tier for $5.99/month, or $71.88 per year.

The offer is only for the first 12 months, though it applies to both new subscribers and ones who are returning to the service. It's also only available to buy until September 18, so few existing users have sufficient time to to cancel their contract and re-up under the new offer.

This does mean that Paramount+ is the cheapest of all the big-name streamers, if you can take advantage of the deal. It compares to an ad-supported Disney tier at $9.99 per month, and Netflix's ad tier of $7.99.

As ever, though, even a tempting price can be worthless. If you are crazy keen to see the new "Slow Horses" starting on Apple TV+ on September 24, then getting the new "NCIS: Tony & Ziva" and just about everything "Star Trek" for less on Paramount+ isn't a savings.

This price cut offer comes as Apple TV+ executive Chris Parnell has been poached to join the Paramount+ marketing team.
