If you have been considering switching to AT&T, we noticed they have offered discount promotions on a predictable basis. At least one weekend a month, and sometimes more, for the last 6 months or so, AT&T has been offering new accounts both Free overnight shipping and Free activation. This amounts to savings of at least $50 and sometimes more. A "weekend" usually means Friday through Monday.
Also, they have been promoting refurbished iPhones as low as $79. The iPhone supply varies from week to week, so you need to check the inventory and the promotions to make sure they're both available at the same time. Of course, there are lots of other good phones to choose from.
These deals have been available from both AT&T directly, or from AT&T retailers like our own Moose Wireless. Of course, these deals can evaporate at any time, and AT&T and the retailers don't always offer the same deal at the same time. We're just hoping we're giving you a heads up instead of giving them a reason to give up.
