My advice: get the drone and don't buy anything else, except perhaps one spare battery.
People get all excited about getting their drone (totally understandable), but they start obsessing over what else they need to get. The problem is this: everyone uses their drone in different ways, and a lot of the recommendations you've already gotten will probably be totally useless for you. On the other hand, perhaps they won't be. However, the point is that you won't know until you've gotten the drone and mad a few dozen flights.
Yes, you can sometimes save a few dollars by buying a kit that has all the things you will, in fact, need. However, if you don't know what is important to
you before you purchase, then buying a kit with lots of flotsam (unimportant stuff) will waste your money, and just give you a lot of stuff that will sit on a shelf for years.
I had already been flying a friend's drone for years before I finally bought my own and had a pretty good idea what I needed. So, even though my friend had five batteries and a huge parallel charger, I realized that most of my uses would be easily covered by having just one spare battery that was fully charged. I needed ND filters for my
M2P, so I got those, but I really didn't need much else.
