I'm 20 weeks and got most things!
I'm not getting things like cot, pram, nursery furniture this time though as we will be following attachment style parenting. We've bought a bigger bed though.
If you want a Moses basket- wait till the last minute to buy, I ended up with 3 last time, and have already declined several this time. Wait and see if you get offered one. They aren't in them long, and lots of babies hate them.
Baby bath-pointless. Heavy if you use out of bath, better to get a smaller seat if you are leaning over bath anyway. Sink is even better! Best for your back and self draining.
Creams, oils, bubbles, talcs and potions for skin are a con. Just use water. Baby branded stuff is full of chemicals. I'd get a natural oil for cradle cap, dry skin, nappy rash. Organic coconut oil does the trick. But if you stick with water you won't get many rashes in the first place.
Bath and room thermometers are a waste of money too.
Baby towels as well, just use big ones.
You just need clothes (vests and sleep suits) don't go overboard on bibs and Muslins till you know if you need them. . I bought tonnes and my dd never puked or dribbled. Nappies, a changing mat is useful but not essential. Blankets, cotton wool or washable wipes, a night light or red bulb for night feeds, and that's pretty much all the essentials.
