search google maps can often locate street in correct suburb. Sometimes buyers mess suburbs if they are borderline. If you have to put diff suburb than buyer address. Eg buyer puts East Sydney, when that isnt offical suburb, then put in box what AP will accept and in the address line put address as per official paypal addy. That way you have paypal addy on there as well as what auto sorting will accept. Usually obvious to delivery centre when it gets there what you mean
