regular visitor, I know the prices , I will buy
2kg ,so come down to Rs 90/kg , if you want
to ….
Sirji !, the stock has just
entered the market , the SUPPLY is less but the DEMAND is very
high !
Why are these mangoes so expensive
??? I wanted to have lots
and lots of these
Every summer the same thing happens
,whenever Alphonsos enter the market their
price is sky high!!!
But Why????
SUPPLY Less
DEMAND High

avilable but mango eaters are more … That is why
the alphonso mangoes are so expensive

Nagpur oranges, Special price for you

How much are these oranges
for??, they don’t look that fresh
Great !! Oranges have now come down to Rs 25, it has been a
month or so that they have come into the market, last time I
bought them it was Rs 40/dozen
So now rates of Oranges have come
down !!! But
how and why ???
SUPPLY Enough
DEMAND Moderate

I got it !! Since there is enough supply of oranges available
and demand for them is moderate ,the price
has come down !!

Fresh and Nice Fruits !!!

best ones ,you know I am a
regular buyer, I know about the
quality!!
