Buy now to setup in a few months

Hello, just a general question - I'm moving shortly and will be at a rental for a few months before we finally move into our "new build" home. There's a good deal going on for refurbished items right now and I was hoping to purchase now to set up everything in a few months. Will I lose out on the free trial if I do that, and also lose out on the ability to add the extended warranty by purchasing the $100/year plan? Or are there no issues with buying now to set up in a few months?Thanks in advance!
