Ship Before the Cutoff Times to Be Safe

In our experience, holiday shipping seasons tend to get crazier every year, with package volume only increasing as online shopping continues to gain footing. All the major shipping carriers are bracing for an enormous volume surge, and even if you ship by these deadlines, there’s a chance USPS may still not deliver your package on time. So, if you’re shipping with USPS, we suggest shipping your packages before the cutoff dates we listed above if you want to make sure your package arrives on or before December 25th. With all the carriers expecting record-breaking holiday volume like in 2020, it’s better to be safe than sorry!
