One of the drawbacks of going with a prepaid carrier is that you have to pay full price for your phone at the time of purchase – no subsidies or payment plans. Going with Net 10 might seem like a more viable option today, though, with an extra $100 off the Moto X via Moto Maker.

Just head over to Motorola's site and choose Net 10 as you carrier. The link in the Motorola tweet will also select Net 10 as the carrier automatically for you. It's the same Moto Maker process other than that – pick your colors, personalization, and get it shipped. This deal is only good through July 16th. The tweet also mentions 50% off cases, but anyone can get that by checking the Motorola store.
