The Samsung Ultimate Test Drive program initially lets iPhone users try the latest Galaxy flagship devices for a month for just $1. Now, iPhone users who buy either The Galaxy S6, S6 edge, S6 edge+ or the Galaxy Note5 after trying out the device will get a $100 Google Play Store credit. The only condition in the promo involves volunteering some feedback via a survey on your experience with the device and the purchase receipt and information.
You can also earn a extra $100 check if you trade in your iPhone via your carrier or retailer. Although you are better off selling your device on eBay considering the average resale value of the iPhone.
