Package drop box large enough for vinyl record parcels?

Has anyone bought a package drop box for their vinyl parcel deliveries?

I have just had my first package stolen off my porch... found the packaging around the corner later in the day while walking the dogs...
I have searched for parcel deliver vaults... but none seem to have a large enough depository (the upper pull-down drop door).
Largest I have found will hold 17"x9"x12"... 12" seems to be the common largest last measurement on all the models I have seen. Have looked at DVault, US Mail Supply, etc.

What have you found to work?
