Speaking of which, why don't someone just sell boxes for peoples homes? You know, some reasonable size container that you can only put things into but not take out of. Wouldn't that eliminate that reason for BufferBox? I think the only use case remaining would be in urban areas where space is at a premium.

EDIT (in response to leddt since I can't reply): if you ask UPS to leave the packages without signing, will they refuse to do this even if they are placing it in a secure place?
