I'd take the LPO out of the list of branch addresses for this one.
I don't have a cite to back that up - it's more a function of customer service. Do you really want folks to potentially go to the LPO thinking they can open a deposit account? Taking the address off the ad may lessen that hassle.
The risk is, you have a staffer at the LPO who tries to provide above & beyond service, and innocently offers to open the checking account right there. Now you're doing branch business but you never applied for permission.
Good luck with the ad -
