Box Of Goodies
This app is handy. The box that pops us is cute and suits our brand. I wish it could be altered to show in the bar at the top and hope this might be a change for the future. :)
Glad you found designs cute and it fits your need! We've taken your consideration seriously and going to present you with some design options for feature your requested. We want to make sure we build it according to your needs and take your feedback during a development process.
Update: Developed and delivered this feature within a week but merchant is unreachable since then to provide an update. Now you can validate zipcodes with the help of header bar :)
