i bought a starter for my dodge ram one time from napa.. walked in asked price.
they asked which unit I wanted / ie.. warranty.
3m was something like 69$
1yr was 99$
lifetime was 129$
they had the starter setting on the counter in the box. .. they only had 1 in stock and I didn't feel like ordering one and coming back another day.. i asked which they had.
same starter .. :) they just rang it up differently based on what you bought.
IE.. smae piece of metal for 69$ could cost 129$
it's not like they had 3, and the expensive one 'looked better' or was built better to last longer. just a warranty / liability 'payment' issue.
I took the 3m one.. ran the truck another few years.. sold it to work.. it's still running.
what a ripoff.. :)
