What are purchases you find yourself making to cope with ADHD? (Other than meds)

Just curious, for my fellow ADHDers, in life - I notice that it's not just medication that's enough for us sometimes.

For the sole purpose of helping/making your ADHD easier to deal with, have you spent money on assistive devices, technology, automobile modifications, home modifications, therapy/counselling, ect. ?

I know this is a loaded question and it can even go in the direction of something aesthetically pleasing to the eye that you feel is essential to get that dopamine-hit to start your day, a membership that directly serves to make your ADHD better.. or even habit-stacking purchases that you do to cope - so I'm really curious to hear everyone's takes.
