When a doctor has a prescription written for a critical condition a pharmacy's employees should not use the USPS when other locations had always had medication delivered in one to three days. Because of this the multi-billion dollar corporation placed a life at risk and,as usual, it's only concern is to make big profits. Quality control does not exist at the location in Pittsburgh, so if you value your life and wellbeing use a different distribution location and a different corporation.
CVS distribution centers usually send out medication by UPS or FedEx but the one in Pittsburgh took a subscription for a critical condition and used USPS, which has taken over a week and it still didn't arrival. Absurbity generated by greed for big profit has obviously driven the life threatening situation.
Save yourself a lot of pain, suffering, and possibly premature death; use someone else.
