Do the rest of you obtain parts from aftermarket, like LMC for old discontinued GM vehicles and resale them , or do you stay away from this and let your customer do their own shopping online ? The customer will see what you pay and if you try to make any kind of profit, some people will complain. Just checking the thoughts out there.

I've tried to stay away, but so much GM original is discontinued and it seems I am turning away too many sales.
