I understand that Kaprys.
Where I live by next month we will have everything that Poland can grow locally in our own back yards too.
That is why I ask where you lived abroad to miss Poland's seasonal fruits and vegetables in the summer.
Shipping does make a difference
It does on short shelf life fruits and vegetables but remember the size of the U.S.A. in land area compared to Poland so some fruits and vegetables have to be shipped.
Some things like Georgia peaches, Michigan black sweet cherries, Florida oranges, Hawaiian pineapples can't be beat in any State, shipped or not.
Does Poland grow mangoes, avocados and banana's that have to be shipped 1500 miles north and taste just like they were just picked fresh ?
The U.S. does so I can't understand where you went abroad to miss Poland's seasonal fruits and vegetables.
