Update 8:28 AM EST: There is a rumor that this deal will not go live until 1:00 PM EST, as it is currently not showing on the mobile platform.
For today only (June 27, 2013), Groupon is offering a nationwide deal with Target. However, there is a kicker with the promotion.
The Target offer is only available for purchase via mobile device.
Unfortunately, with it being mobile only, you will not be able to use any of the cashback portals.
