OK to negotiate with Closing Attorney/Title Agency when doing multiple flips?

[Thomas Johnson]

We do 7-8 flips a year and always use the same local closing attorney.  I'm wondering if it is common to negotiate closing attorney fees due to repeat business for the CA.  When we purchase a property, we have CA fees (title search, owners title insurance, lender's title insurance, attorney fees, etc.) and when we close/sell a property we again have CA fees.  Thanks for any thoughts or input on this.
