Today's Sim's Delivery express?

Thank you very much, @Peppers and @Stormkeep for clearing things up for me. This is what I was afraid of as soon as I began doing a bit of research. Sigh. I guess I'll be playing offline for a long time. I had hoped the updates and the Sims Delivery were separate entities, but that isn't the case if using Sims Delivery will trigger the updates to download. I've had very little spare time to look at this more closely, so I appreciate your quick responses. You saved me a couple of hours' worth of investigating. :)
