You will be able to print it out or show the certificate on your phone at the time you come in to redeem it. In order to redeem, you will need to have an ID that matches the name on the certificate, so be sure to fill that out section properly. We will have a database with all the info to reference, we have to protect ourselves from fraud the only way we can. Please remember we are just a mom and pop store doing the best we can and even though you are honest and righteous, there are people out there who certainly look for loopholes! Any questions, just email and ask!
