Unfortunately just about no one india buys these miners because of a few reasons.
1. They dont know about mining
2. They think it is dead and not profitable.
Now even if someone did buy these, it would be in a limited quantity for personal use and no one is going to sell a PSU off from their miner locally.
I know this because importing these miners to india from china has a very lengthy procedure that most people dont know how to follow, even bitmain official website does not ship to india because of this.
Even if someone manages to do the right paperwork and manages to find the right shipping service for it, its still going to be a hit or miss because sometimes the people at customs end up stealing the package. (unless you know how to deal with it *wink* *wink*).
The way i managed to import these miners to india is because i have some connections with the people at the customs and i simply ended up getting lucky and found the perfect seller. You can see my journey through that here :
