Aliexpress is still banned in India? Any alternatives?

What do you want to get? Individual sellers from SEA still ship and I can suggest a few

Accessories for my iPad. Keyboard, case, etc.

Ah aliexpress is great for cheap stuff. I assumed you wanted to get something expensive, but it won't be worth buying something cheaper since Customs will be around 2-3K. Better to buy from amazon.in itself If (item cost + customs) < indian price -> check singapore shops. Friendly and trustworthy and you can message them, they'll send by Singpost
