I bought this pair of melons grown in Guatemala at a local U.S. supermarket for 
$1.98 a piece. They were good, but not great. I placed a little salt on each to compensate for the lack of sweetness. The Guatemalan cantaloupe has gotten better as the season has progressed, not unusal for a lot of fruit, not matter where it is grown.
Now get this. In Japan, the Yubari King melon is what Kobe is to beef. Yubari is a Japanese city famous for cantaloupe that is a cross between two varieties. A Japanese auction has gotten as much $26,000 for a pair of these melons! However, the “regular” Yubari melons more typically garner “only” $50 to $100 a pair!
Think I’ll stick with my Guatemalan melons, even if I do have to add a little salt.
