I'd recommend getting some Edison Style LED light bulbs, right now they are 30% off for Prime Day. When I got my house I upgraded all the bulbs in the house to them, they use ~1/8th the amount of electricity and are not supposed to wear out (Since my first house in 2014 I have never had to replace a single one), as well as being completely dimmable and providing instant light (unlike the awful CFL bulbs), and can choose the warmth you want for each room... And they will save you money in the long run.

As well as some smart home stuff, I just bought a new Echo and the Echo Auto (50% off).
