No.
Most have some kind of return policies, especially when one buys online. I have enjoyed the same here in India when I bought my amp, as already described in one of my previous post. Thanks for your links, however, I have already written about this kind of return policy in my posts above. I have also described how for certain articles (like a TT cartridge) this return policy is not as generous, quite understandably so.
This is certainly not the same as a home demo with no strings attached. As I said, some dealers would still offer a home trial to some customers whom they trust, but I do not know of any dealer having home demo as a general policy with no purchase made upfront. The closest they can come (as far as a general policy is concerned) is for the customer to purchase first, then try at home for a period of time and then return the item without restocking fee (for example, see here Magneplanar Mini Maggie). The volumes are much larger there, so they may be able to do this with a few of the anticipated hot items for a limited period, but the question obviously remains what do they do with the returned items, what happens when some items are returned in less than perfect shape. Somebody somewhere will have to pay for it, and the sooner we understand that, the better it is.
More than thirty years ago, any thing could be bought, used (rather abused) and returned from Departmental stores in the US. Anything really means anything: shirts, umbrellas, electronic home appliances, even underwears. I have seen large scale abuse of this system not just by Asians, by Americans as well. I have also seen large scale abuse of free social benefits in Germany in the late eighties, especially when it came to health related and unemployment related benefits. There is no reason to think we Indians are the only species in the Universe to abuse a good system. Times had to change, and they have, both in the US and in Europe. As far as I know there are now more stringent checks to avail some of these benefits.
In an ideal world, the seller and the customer know their respective responsibilities. In such a world, the above benefits are good and will work. But we do not live in an ideal world.
There is no reason to think that I am trying to defend the dealers/sellers. There obviously has to be equal protection of customer interest. There exist a lot of gross violation of customer interest with people getting ripped off, as we all know and have suffered at times. But that is not the subject here, and we can discuss that some other time.
Finally, I want to reiterate the main points again. If you happen to be friends with a seller or the seller has faith in you for whatever reason, you may get certain benefits like a home demo with no strings attached. I do not think there exists any difference regarding this issue between India and any of the Western countries in general (there may be a few exceptions here and there both abroad and here, but they do not form the general trend). But what needs to improve in India is a consistent policy of returning stuff like our member "that guy" has given examples of in the above post. But no system will survive unless both the seller and the customer behave responsibly.
I have no knowledge of finances, business, management and most commercial issues. I am writing only my direct observations and conclusions made therefrom, conclusions which seem reasonable to me
