After recently running deals on the iPhone and iPad, T-Mobile is now kicking off an offer on another Apple product.

T-Mobile today launched a deal that’ll get you $50 off the price of an Apple Watch Series 3. To get this discount, you’ll need to buy the Apple Watch on an Equipment Installment Plan (EIP) and activate it with a qualifying DIGITS plan. Once you do, you’ll get $50 worth of monthly bill credits.

This limited time deal is available online and in stores, and both new and existing customers can take advantage of it. All Apple Watch Series 3 models qualify for the $50 discount, including the 38mm, 42mm, and Nike+ variants. Pricing for the Apple Watch Series 3 starts at $399.99 for the 38mm versions and $429.99 for the 42mm models.

One other detail about this deal that’s worth noting is that it’s not stackable with the offer of three months of free service with the purchase of an Apple Watch Series 3. With this offer, you get three months of unlimited LTE data on your Apple Watch for free, and after that you’ll pay the regular price of $10 per month with autopay.
