But my existing subscription isn't ending till a couple of weeks from now. Even though I purchased Deluxe a week ago, how long will it be good for?

You can go ahead and put the code in now and it will add a year to the time you have remaining. You don't have to wait until your current subscription runs out, you don't lose any time off your current sub.
Edit: Unless you're changing subscription levels; I'm not precisely sure what happens in that case. But the code you purchased a week ago will still be good in two weeks so if you just want to wait until then it won't be an issue.
No, no changes. Thank you for your quick reply. Best regards, Bob
