Dear Guru
comments are free but facts are sacred
what Mr Natureworx said might work for home garden ,very small scale farms ,farms that are close to cities,farms with multiple crops/vegetables,regular supply
people are required to sell those products one regular basis
just for calculations, lets assume you have 1000 friends/relatives which is unlikely(i have around 15-20 friends and some 50 relatives)
you want to sell your 15 tons of water melon
so it comes around 15 kg/person/friend/relative, what will he do with 15 kg watermelon?
also that retail thing works out when every one wants watermelon during stipulated period of time(shelf life of watermelon) otherwise you have to store that
most importantly friends and relative will want your watermelon,but for free
unlikely to get any payment
even if you own a supermarket daily retail sale of any product(apart from rice,onion tomato…) will be limited to quintols not tons
also logistics issue, one friend will be in electronic city and another in nelamangala, while carrying you can pay traffic police two big watermelons as bribe

you can convince your friends a watermelon a day will keep everyone away 
put watermelon on ebay -as award winning watermelon
sell it to political parties to throw at each other >:(
Get blessings from swamijis like shree Nityananda swamiji etc 
fun apart
only take your products to mandi/apmc/markets if you are well versed about business in such places, otherwise a lot of headaches(loading the products,unloading,transportation, sometimes prices fall ,you will have to wait to sell products, payment issues)
it is better for absentee farmers/white collar farmers to sell products at farm,get money there itself.Till you get hold of farming and marketing
We all can learn if Mr Natureworx explains how it is possible to sell large quantity of products in retail
price difference he got by selling mango directly
how he kept his 4 tons of mango? without mangoes going bad
any hurdles/problems he faced and how he rectified
thank you
