Not yet. We build in a buffer for exactly this, which is why the kit leaves days early rather than the day before.
Text (732) 555-0199 with your tracking number and we will chase the carrier ourselves. If it genuinely is not going to arrive in time, we ship a second kit overnight and eat the cost.
Nobody has lost an event to this. We would rather send two kits than have you find out on the day.
Two minutes, and you'll know either way.
