usps is for sending basic mail. i never ship anything with usps anymore. they loose money every day that they are open. you think that usps really cares about your package. the last thing i send via usps i wrote "fragile" all over the box and then i gave it to the guy at the post office and asked that they try to use some care with it because there was fragile parts inside.. they said ok and proceeded to throw my package into their giant bins 15' away from them...they said, it has $50 insurance...parts inside were over the insurance cost. i was pissed, talked to a manager, they told me "thats how it is, just package it right and there will be no issues". i will never send anything via the USPS anymore. NOTHING. they ****...lesson learned. hope you get your stuff figured out.
