@Mykol - If you have a hard time finding this fruit in your area, you might try buying this citrus tree from a nursery and planting it in a big pot indoors.
I bought a small tree from an online nursery and thought it would be a fun thing to try. My tree keeps growing, but I have not had any fruit yet. I have only had it for about a year though, so am trying to be patient.
If you were able to buy a bigger tree, you probably wouldn't have to wait as long to get some fruit.
Just thinking about it makes my mouth start watering for some of this delicious fruit. My daughter lives in California, and is able to eat this fruit on a regular basis.
Even though it costs more than buying grapefruit, it is worth paying a few cents more once in awhile to enjoy the sweet, citrus taste.
