Use Samsung Pay before May 10 to get a $30 gift card (US only)
Between April 15 and May 10, if you live in the US, you can receive a $30 gift card after you complete 3 purchases with Samsung Pay. However, you need to "have already registered for Samsung Pay before the commencement of the Offer Period, but have not yet made a purchase using Samsung Pay" - thus, folks who received a gift card following last month's promotion are not eligible. To qualify for the offer, you must own one of the following Samsung smartphones: Galaxy S7, Galaxy S7 edge, Galaxy S6, Galaxy S6 edge, Galaxy S6 edge+, Galaxy S6 Active, or Galaxy Note 5. Make sure to read the full Terms & Conditions at the source link below.
