One week ago now, Samsung officially launched its Ultimate Test Drive, a chance for iPhone owners to try out a new Samsung phone for up to 30 days all for just $1.

The promotion is pretty straightforward, but the biggest hurdle at this point is a limited quantity of devices, as Samsung’s stock quickly dried up almost immediately after the promotion kicked off. While Samsung works on adding more devices to the stockpile, so more iPhone owners can test out the new hardware, it’s sweetening the deal for those who are already taking part in the test drive right now.

Samsung has confirmed that a $100 Google Play gift card will be provided to those that buy the Samsung device they ordered through the Test Drive, which is good towards apps, movies, games, and more. To get the $100 credit, a proof of purchase is necessary to show to Samsung, as well as the participation within a quick survey to go over the experience you had during the promotion.

That’s not all, though. Samsung will also send a test driver a $100 check if they show that they traded in their iPhone to a carrier or retailer.

Nice additions, especially for the test driver that actually likes the phones and keeps them. Did you get into the Ultimate Test Drive?
