Samsung is making yet another effort to get new customers for its Samsung Pay service. From Friday, April 15 to May 10, anyone in the U.S. who has already signed up for Samsung Pay and makes their first three purchases will receive a free $30 gift card.

The promotion site for the deal focuses on the fact that the free gift card offer is only for people who have already registered for Samsung Pay before the offer begins on Friday, but who have not yet used the service. This is clearly meant to encourage people to actually use Samsung Pay for the first time.

The actual gift card can be picked for one of four retailers: Best Buy, eBay, GameStop or Regal Entertainment.
