Re: Importing address book entries for multiple customers?
for the sake of brevity I must confess that each customer having 190 store addresses in there account might not be the best idea. Perhaps simply creating a custom or modified shipping module where they can select the store they wish to ship to / pickup from during checkout would be more ideal.
if you still require all store addresses to added to a customers account you can do so by creating a php script to run through all customer account ids and add them to the address_book table. This method is going to cause you headaches because I think its going strain the current address listing methods used by zen cart when they go to choose an address. The more I think about it the less I want to show you how to do it as it just isnt a user friendly, or appropriate way to accomplish what I imagine the client is actually looking for.
all the best,
