If React: Decoded isn't useful to you, email me within 30 days and I'll refund you in full. No questions, no form, no explanation needed.
Email damianboni@gmail.com from the address you bought with. That's the whole process. Refunds go back to your original payment method and usually land within five to ten business days, depending on your bank.
Web access bought through this site. Your access ends when the refund is processed.
