Samsung's Galaxy Watch is a worthy alternative to the Apple Watch, especially if you're already a Samsung user. For T-Mobile customers who activate a new account with a voice line and add a data line, the carrier will throw in the smartwatch for free. The discount comes in the form of 24 months of monthly bill credits. Fine print here.

This is a classic BOGO offer for two Galaxy S9 phones, which means that it's yours when you jump through hoops of fire while blindfolded to meet certain requirements. Ok, so it's not really that bad, but you should make sure you're aware of the restrictions. For example, you need to buy both phones through AT&T Next's installment plan, and the offer requires you to activate a new line of service. You'll be reimbursed for the price of the second phone over 30 months of bill credits, which begin within three bills.
