For the Medication History Certificate, utilizing the second pathway is the cheapest as it only requires 12 months of related experience.
As for the Technician Product Verification Certificate, there is no way around the finances as it requires you take a program online or in-person. I can not speak to the live-programs as I am not familiar with any. As for the online programs, I went with C.E. Impact as it was (at the time anyway) the cheapest option, plus I thought that their curriculum was very good and prepared me well for the TPV certificate test.
