I ordered 2 front rotors for my 08 Focus, for some reason ordering a quantity of two (2) rotors shipping would cost me $33, but if you order a quantity of one (1) rotor it would only cost $8.99/ per rotor so $17.98 for two rotors (so I did two separate orders). Just odd the shipping quotes do that. I know rotors are heavy items but still weird that it's nearly double the cost for simply putting a quantity of two.

I would have ordered pads also but the pads I wanted couldn't be had from the same warehouse has the rotors (different warehouses means higher shipping). I added all the rotors and pads I liked to a cart and as you delete the items from different warehouses the shipping warehouses actually changed locations. Like most I'm just trying to save a buck but the logistics for the shipping quotes and warehouse locations seem a bit buggy and could be streamlined. Ordered pads I wanted from ebay in the end.

I really can't complain, got the rotors in 3 days, netflix isn't even that fast sometimes and they just ship CD sized discs out.
