Because its holiday season, there have been numerous delays with packages.
Express Mail International usually takes 3-5 business days; however, all shipping times are estimates given by the shipping company -- UPS, USPS -- which controls how fast your package gets to you.
Nonetheless, for any order related issues, always submit a support ticket directly at
www.theory11.com/support. If your delivery time falls outside of the estimated range, give the support team a buzz -- the support guys will try their best to find out exactly where the package is and when it should arrive.
Cheers,
