This week at a local market in London we purchased these 22 fresh avocados for a total cost of three quid. When I worked out the exchange rate (a bit less than four U.S. dollars), that total came out to be just about 1/15 the cost, per avocado, of the most recent avocado I purchased in New York City.
I am happy to report that all the avocados were perfectly ripe and delicious. We made lots and lots of guacamole!

Where was this?! These are not ordinary prices!
This was at the market near Clerkenwell. As to the wonderfully low price, I suspect the lady selling them was trying to get rid of them before the market closed.
