Prime Benefit (YMMV): $5 Gift Card the First Time Ever you sign-in to Amazon Shopping mobile app

This offer is available to Prime members, and it is targeted to individual Prime members – check your emails to see if it’s anywhere in there. If you have never signed in to the Amazon Shopping or Underground mobile apps, you will receive a $5 Amazon electronic gift card 7 days after you sign-in to that app for the first time ever. This does not include the Kindle or Music or Video apps, but only the specific Amazon Shopping and Underground apps shown at the promotional page. Promotion ends 11/19/15.

PS: this is a low risk to check, but keep in mind, the Amazon apps have not met an Android system permission they didn’t like 🙂
