Taking a visiting devotee (from USA?) to buy from a store that charges more money or sells substandard, acting out of greed, for a kickback later from the store owner.
I had a friend who bought a clay Mridangam for approx $150 US dollars from Mayapur, India
from a store recommended by a devotee friend he made while his visit to Mayapur.
I remember paying 600 rupees or $12 US dollars each or Grand $48 for 4.
Felt great giving couple of them away. This was 6 years ago, when I visited Mayapur.
Sure prices went up over 5 years, but not 10 times. He got ripped off.
If you are going to get a kickback, please disclose. Not cool!
