Since Samsung Pay had offers earlier this month for free Pokemon Go Shop codes, they are now allowing you to use Samsung Rewards Points to make Shop purchases. You will have to download the Galaxy App store version of Pokemon Go, which will also give you a 10% discount on Shop purchases from now until 25 May! It is the same version number as what is presently in the Google Play store (0.175.1). You can get 550 PokeCoins for 998 Samsung Rewards points. With the 10% discount, it actually comes to 898 Samsung Rewards points.
Once you download Pokemon Go, from the Shop, select Samsung Pay as a payment method. Then click Use Discounts, directly under the payment method. Click Samsung Rewards, if you have points. The payment screen will now show how many points will be deducted for the purchase. Total should be $0.00.
Hopefully this is another option for those of you with points and not a lot of options of what to do with them!
