Parts rant

I dont know what shops are doing. Local parts stores dont have common parts for a 2005 camry. I have to shop Rock Auto for basics. Their shipping has been decent.
I had to buy a cat back exhaust from Canada via ebay, under 200 bucks. VS dealer bargain price $1900. ( 3. 02 sensors partial zero emissions vehicle)Ebay's shipping is not accurate and I'm only 2.5 hours from Ontario. I hope it's not several weeks but I wont die either.
