You have 2 days after your event to hand the kit to a carrier. Not to have it arrive — just to hand it over. The clock stops at the first scan.
Past that it is $75 a day. That is not a penalty for its own sake: each kit serves one event at a time, and a late return can cost another couple their date.
If something outside your control delays it — a carrier closure, weather — tell us before the window closes and we will not charge it.
Didn't solve it? Text (914) 825-5498. If it's your event night, lead with that — those go to the front of the queue.
