When I need to order something I Googled it and get the best price if possible. Lots of Etailers are aboveboard but not well known. So far I haven't had any problem.
I'm pretty leery of EBay so I don't buy from there.
I actually did not replace the old pads when I did the rotors and I did them just cuz I couldn't find original or OEM quality rotors. Now that I found them in only one store I decided to just replace them now with the pads. My only choice was to get them online before, and I hate that. Local purchase turned out to be cheaper anyway. What's wrong with those online sellers trying to fool me like that?
