December 1st-4th: All shipping methods except U.S.P.S. First-Class Package International Service™ are safe. December 5th: International orders made not selecting U.S.P.S. Priority Mail Express International™ shipping will likely arrive in January. December 10th: USPS FIRST CLASS and STANDARD may not make it in time and neither will USPS EXPRESS MAIL INTERNATIONAL.
