I am having an issue with the rear deraileur on my bike. The shop is trying to charge me $100 for a new part. i was wondering if anyone knew the exact part so I could try to buy it online

Thanks

Your description is a bit vague... are they saying you need a new derailleur, new derailleur hanger, or something different altogether?

If you're not sure or not up to speed with bike part terminology, maybe post a picture?
