Question: How will I receive my products?
Answer: Products are delivered within 48 hours after payment through our site's built-in systems. Within 48 hours after payment, you will receive a PM leading you through the delivery process. The 48 hours start once the payment has reached our end. Orders may be delayed by holidays. You may request expedited delivery from sellers. Some of our sellers do offer faster delivery for a small fee.
