Q: Radiator replacement costs 1998 Toyota Camry

My radiator got a crack on the top plastic portion and started to leak coolant. On Google, I was able to find many DIY tips for the radiator replacement for Camry 98, which would cost under $100 for the part. Because the leakage seemed severe and urgent, I decided to bring my car to a local repair shop, instead of fixing it by DIY. The mechanic told me that it is not recommended to replace the radiator only, and I had to have the hoses, thermostat housing and thermostat replaced, along with the radiator. In the end, they charged me $473.86 for parts and $286.90 for labor, which was far higher than I originally expected. So, I searched for the parts on NAPA based on the part numbers on their invoice, and found that the NAPA price is around $200 in total. I understand there can be a price mark-up for parts by the repair shop, but it seems too excessive to me, because the mark-up ratio is over 100%. Was this normal mark-up ratio, or was I ripped off?
