In the past 10 days cherries were purchased at the following prices:
1) .99/lb at a Brooklyn F&V store
2) 1.99/lb at a Manhattan sidewalk cart
3) 3.99/lb at a Manhattan supermarket
4) 4.99/lb at a fancier Manhattan F&V store(Listakos)
The quality and taste were remarkably similar, though the sidewalk cart's cherries were lighter red on average. Any explanation for such a price disparity?
