I find it amazing that there is now 200 banknote and then only 2000. And there is only a moderate amount of the 200s not the crazy amount that is required for giving 9 200s as change when you buys something worth 200 with a 2000.
The notes in circulation currently are only the old Rs. 100 notes and a few new Rs. 2000 notes. You are right that for small to moderate daily purchases costing between 500-1500, it does not make any sense. The new Rs. 2000 notes are essentially useless for now since no one can give you change for that.
As far as I am aware, there are no 200 banknotes. The last time I visited India they had hundreds and five hundreds, no two hundreds.
