Did they send it USPS retail? My postmaster told me to never use that because they take the long ride. She advised me to always use Priority Mail 2 day shipping to send a kit. That way there is a tracking number. Insurance. And has a more direct route to its location and the package gets less hands on time. And I always send a photo of the package with the shipping label on it so the buyer can see what condition it was in when I sent it out.
