Thank you for visiting Sparrow Dynamics! Please email [email protected] requesting a coupon code to use once we are back online. Our payment processor recently sold their business and shutdown their payment gateway without warning. We are working as quickly as possible to switch to a new payment gateway and connect it to our bank. Progress is good, and we plan to be back online on or before May 1st . Thank you for your patience and support! Please contact [email protected] for any questions.
