When i place an order i encrypt my address to the vendor, that way on one is gonna have it but the vendor. To be safe if SR get compromised you don't want one of your shipping address being one of the ones not erased yet because the vendor has not confirmed shipment. I also encrypt all PM messages as well. Search PGP on the forums and It will give you step by step on how to set it up and once you use it ince or twice it just as easy as email. I know it's overwhelming at first but becomes second nature quick.
