Once you accrue the required number of points (15,000 points), you should be able to redeem them for cash credits.
1000 points = $1.
To redeem, simply open the “Rewards” tab, and under the “Winnings” sub tab tap on “REWARD POINTS”. There you can confirm the total points you’ve accrued and tap on the “Redeem To Cash” button to convert 15,000 points to $15 in StoreCash credits. You can use these credits towards your next purchase.
