Samsung has launched a new promo so if you make at least three purchases using Samsung Pay you will get a $10 Amazon gift card. The promo is available to both new and existing users.
There is no minimum purchase amount, as well as no limit on number of purchases that can be made in a day, meaning you can make all the three purchases in a single day and get the gift card.
Available only in the US, the offer has just begun and runs through August 1. Only those on the Galaxy S6, S6 edge, S6 edge+, S6 active, Galaxy S7, Galaxy S7 edge, Galaxy S7 active or the Galaxy Note5 can avail it.
