Too much invested for strangers to come handle a snake they "may" want to purchase. Not taking that chance even if it means a missed sale from someone local.
I have made 75% of my purchases only seeing pics and texting/talking on the phone. A few purchases sight unseen (pics or anything) from breeders I trust. 100% of my sales are forum/internet sales. If you think people are not interested in stealing from your collection, think again.
Numerous cameras on a 1TB DVR system with and a full blown security system with motion detectors, glass break alarms, and welded rebar over the windows are in place (along with an armed owner when at the facility). I do not live in a low rent district, but it is a tourist town. We have about 250K bikers in town right now for Bike Week and a few hundred thousand people a couple weeks ago for the Daytona 500.
My gf does not even have the security code to the alarm system..... I trust no one.
