LoveBubble,
I like that name. ;-)
To answer your ?'s: Have the person sending u the package check the box that reads "No signature required" or "Signature Waiver", i'm not exactly sure how it reads, but it's close to what i have listed.
Also, i believe if one doesn't use express &/or priority mail, then NO signature is required regardless.
The 48hr time frame is a safety thing. Just in case the package is being followed (very doubtful), the authorities will act within 24hrs if they have a search warrant. That usually is the amount of time the warrant is good for. They will want to seize the offending compounds at one's residence, b4 one has time to transfer them to another place & they lose the "trail". That is usaully why the authorities act w/in 24hrs.
The extra 24hrs i added on is just for safety's sake. One can never be to paranoid...it keeps u safe.
