We ship our boxes using USPS 2-3 Day Priority Mail, and will do our best to make sure your box arrives on or before the date you choose. However, since the postal service does not guarantee the delivery dates on that service, neither can we. They typically do a great job of getting the boxes delivered on time, but we encourage you to add a little buffer to future orders, just in case. By selecting a future date below you acknowledge this disclaimer, and agree to hold us harmless if your package arrives after the day you select.
