The USPS is quite useless. Pony Express was faster. I've been sending oil samples for ~7 years (not to Blackstone), I use Polaris labs and UPS my samples. Online tracking, they are always there overnight (unless weekends) and I get results emailed within 2 working days.
Over 1 week is unacceptable.
