Buy from Ordinary Street Sellers; be it a cart-man, small kiosk shop or a person sitting on floor. They are usually the Sole Bread winners for the Whole Family.
Don’t argue on price, just buy – Your few Rupees may arrange some food for a child.

Charity will provide for one time only; Buying will ensure Long Term income source and the poor will keep his dignity & honour!
