So you can but Monkfruit online at Amazon/ebay and a range of physical stores in the states such as Walmart. But its the powder not the fresh fruit (because then you'd have to dry it and powder it before use in most foods/meals anyway...)
I buy them here from my local supermarket. And our 'super'markets are tiny compared to yours ...lol...
There area few different brands about too
There's also this called just like sugar made from the Chicory Root which I found in 2017 and got it shipped to Australia from Nevada and it's not too bad, though it does have that odd after taste, but no where near as much as the synthetics do...
Very interesting...
Actually I'm not sure if you have seen this video, but its actually really good as an indication of all of the alternative sugars on the market today.
