Payment update & VIP rewards — October 16, 2026
In its October 16, 2026 update, Double R Labs announced that Visa and Mastercard debit cards are accepted again at checkout. After a successful debit purchase, the payment system may recognize a returning customer and allow traditional credit card payments on future orders. Customers who have already used a debit card through the new system may already qualify. Future credit card acceptance depends on processor eligibility and is not guaranteed; broader credit card processing is still being restored.
