The prices that I got myself were before my discount, after my discount it'd be 20% off the prices I mentioned earlier... that's the regular joe customer price.
And I dont know where these guys get their parts from but I know we give commercial accounts a fairly steep discount as well, and most of them are tax-free
I guess also part of what ticks me off is that I know of a few smaller, privately owned garages that I feel would've done better work for cheaper, vs the big successful chain garage
