19 filters for a total of $43.35, retail would have been ~$150
I do have way more filters for the Scion than I need, about 7 years worth. It was a shared filter size with my mother in laws vehicle, but she sold it.
One of the Bosch filters I am not going to use, it has louvers in the center tube that are not very opened up.
The filters for the F150, well I service 2 F150's, so I am fine with 4 of them.
The 3593/9688 size filters fit 3 vehicles I service, so having 6 is not a lot (but in the future will probably just stick with the ST9688).
The filters for the Santa Fe I got online in a 4 pack, about $3 cheaper per filter that way.
